That you take it off

"I wish that you take it off then!" She tells you with a smile, and watches while you fumble with the collar with your thumbs without lifting your palms off the desk top. You're not even sure how you do it, but somehow the devious thing comes right off and lands on the counter.

"Oh, thank god!" You gasp in relief as you can suddenly stand upright again, no longer compelled by the strange collar. Then, before you even got the chance to stop her, the young clerk picks it up and snaps it in place around her own neck. "Eh, what...?"

"Now try me then!" She chuckles, obviously still thinking that it's all just some strange kind of joke. "But remember you need to say 'I wish'!"

"Uh, right..." You mumble, noticing how a few of the customers are now becoming a little more interested and has started watching the strange exchange between you and the clerk.
