Start with the owners

The vampires surveyed the room. With few words and many knowing glances they divvied up the attendees and forged a battle plan. Pete went over to Ursula as she was finishing up a phone call for a Saturday reservation.

"8 o'clock... party of 4... Yes... That's not a problem," she put the phone down then looked up from her schedule book. "And how may I help you."
Pete faked an innocent smile, "I need to ask a favor. Today is my anniversary." Ursula was mildly acquainted with the couple and remembered his earlier call about the anniversary. She nodded along. "This is our wine from our wedding day," he lied holding up the vampire wine that started his family's new lives. "It's 25 years, and we want to finish it up and then purchase a bottle of your finest wine to open 25 years from now."
Ursula grinned and how romantic that was. "That's so sweet. I have to warn you that our collection of wines is limited. Most of our patrons go for beer, vodka, or bourbon. Though I do have one in the cellar you might like."
They made their way through the employee entrance, gaining notice of Anthony. He was always extra observant around his wife as he suspected for some time that she had a wandering eye, though that was all just a feeling without proof. He turned to follow after her until JJ sauntered up to the bar. "Oh, sorry. Are you looking for something in particular?" he asked of her. JJ let the question hang to be as suggestive as possible. The owner wasn't biting and JJ noticed. "Jack and Coke," she told him dialing back the flirting. Anthony's restraint was not due to him not finding the professor beautiful or a lack of desire to impose his physicality on her, but his moral code was unwavering. Still he was distracted enough to allow Pete and Ursula to venture downstairs unimpeded. At least for now.

Will and Michelle Kirk, aware of the movement of all the pieces in their game, took this moment to make their way to a couple at another table as Sophia waited on them. The Kirks and the Van Pollard couple knew each other from the country club. Each were similar in that they put a premium on appearances and status. In fact it was the Van Pollards that dissuaded Pete and Hannah from joining the country club (something the Kirks had pushed for some time) as the Van Pollards were stuck up to the nth degree.
"Angelique! Ford!" exclaimed Michelle Kirk in fake surprise.
"Michelle, darling. How good it is to see you here," Angelique said with emphasis on the word "here". This bar was not a dive by any means, but it wasn't the country club. Still all four understood that in the middle of the week entertainment options were limited and a quaint night out was better than nothing.
The two men shook hands and Rutherford "Ford:" offered the couple seats at their table. Will Kirk planned what to say when they asked why they were there, but no such question came as Angelique had already started a story about a mix-up with her dry cleaner. Amidst all this was Sophia, the waitress. She was focused on the two couples in front of her that she didn't notice the mother and daughter from the anniversary group had slipped away. She chalked it up to them going to retreat to the ladies' room. What she did not know that only the daughter, Becky, had done so. The mother, Hannah, had slipped through the employee door a few minutes behind her husband and Ursula.

In the restroom Becky waited in the dark to strike when one of the customers came in. She hoped to pick a few off one-by-one before night's end, but to her surprise none had come for several minutes. To her delight she heard another noise from the men's room through the wall. It was Dominic, the piano player, who had taken a break to relieve himself. She crept in light night itself. He stood at the urinal hummin one of the songs he'd just been playing minutes earlier. Becky had been on the volleyball team with Sophia the year before, back when they were both in high school. She didn't know if the rumors about Dominic and she were true, and the old Becky never would have gone after a man if her friend or teammate was with him. But this was the new Becky. There were no trusts that couldn't be broken, not with blood and flesh in front of her, Before he could zip himself up he found the young woman with a light grip on his crotch. Dominic was clearly not the sharpest tool in the shed, but it didn't take him too long to figure out what she wanted. At least what he thought she wanted. His size down there was impressive for a human. If Sophia was with him she picked a good specimen, but vampirism had spoiled her. The transformation into a bloodsucker impacted the body, both male and female. After spending the night with her father she was looking for a step up. She avoided his cock entirely and used her fangs to bite multiple times into his thighs and once into his sack. This level of pain he felt far exceeded the amount of pleasure he expected. She then used her tongue to make sure not a drop of blood was wasted. She then stood up and kissed him on the cheek and whispered, "Forgeeeet"
