Pfft, I'll admit to it. My best friend from my ITP and I were at a gym where they had completely screwed us over on our contracts (in fact everyone associated with our accounts ended up getting fired). We were having a meeting with the incredibly sleazy manager who was giving us the runaround and so forth. Every time he had to take a phone call or go talk to someone else or whatever, she and I would start up a conversation in sign all about him and what a jerk he was and what we should do about it.
It obviously threw him off because here we were, clearly not deaf (nor, of course, pretending to be), and yet we were having these signed conversations in front of him. But we were more than happy to unnerve him since he was bilking us out of our money.
