Get behind the counter

You wait a minute until she's once again completely overwhelmed by the amount of people around the counter before you decide that it was time to get a bit closer to her. You go to the entrance and step behind the counter. She hasn't noticed you yet, so you go over to her. "Your boss told you to do anything to keep the customers happy, right? That would include accepting some help, so take a step to the side so that I can reach the tap." Her mouth was already open to protest, but she quickly closes it and gives you a thankful look. Together you hand out one beer after another and you think that you'll actually be able to do it this time. Working so close to her, you get an idea. You start to touch her seemingly randomly every now and then and while she flinches the first few times, she gets used to it after just a few minutes and when you hand another regular a beer, you get another idea. You signal him to stick around and when she's distracted you quickly explain your plan to him. He looks pretty sceptical but then he shrugs and agrees. It's not like you have anything to lose here.
