A few basic ones to get started

"Mackenzie, any time I say 'sleep' you will instantly feel extremely tired. You'll let me put you back into this deep trance. And every time you wake up from it, you'll think you just dozed off for a minute."

That should make it easier to add new commands. Amanda thought, her mind already running wild with the possibilities.

"Also, you'll completely forget that I ever put you under hypnosis last night. If you think anything isn't making sense to you, you'll believe it's because you're tired and didn't get enough sleep last night."

Hell, may as well go all the way with this, Amanda thought.

"Whenever I say 'trust me,' you will implicitly believe whatever I say. Do you understand?"

"I understand." Mackenzie said in her monotone voice.

"Great! Now on the count of 3 you shall awaken from your deep trance. 1... 2... 3!"

Mackenzie sat back upright and rubbed her eyes.

"Wha?..." she said sleepily.

"You dozed off there for a second Mack, you must be tired."

"Mmm sorry." she said, taking in the diner, "Yeah I guess I am pretty tired. I don't think I got enough sleep last night."

"Are you gals..." Charlotte began as she approached the table again, only to trail off at the sight of the shirtless Mackenzie. "Uh, what happened to your shirt, miss?"

"Hm?" Mackenzie said, confused. She was dressed perfectly fine after all. "What do you mean?"

"She's a bit of a free spirit," Amanda said, "Don't worry about her."

"Uh... I guess that's alright." Charlotte replied, "But if my boss sees you without a top on he's liable to throw you outta the place. Just a heads up."

She took their orders and headed back to the kitchen.

"What was that about?" Mackenzie asked.

At that moment, someone across the restaurant shouted "CHECK PLEASE!"

"I'm not sure." Amanda said with a smile as Mackenzie began shimmying her leggings down her legs. "But I wouldn't worry about it. Trust me."

"Okay!" Mackenzie said cheerily, now sitting across from her friend in just her bra and panties.

Already, Mackenzie was drawing stares from her fellow diners. It was plain for almost anyone to see that she wasn't wearing a shirt, and a select few were also able to see that she wasn't wearing any pants. Amanda thought about having her put a few things back on, lest she actually get kicked out of the diner. But on the other hand, maybe she should just have Mackenzie go all the way...
