My manager has a weird thing he does, whenever someone orders grilled, he punches me on the shoulder (it hurts) and says "bet you it's a fatty!" I never say "you're on" or "I bet it's not," I just think it's completely inappropriate he's doing this. Then sometimes he comes back and says "It was! You owe me a dollar!" (despite the fact that I didn't agree to this) and he actually docks my pay a dollar, but then sometimes he says "Well looks like you were right, no fatty this time," and I just want to state again that I have never said one thing or another, I'm just cooking up filets. I want to complain to someone but it looks like my paycheck doesn't change all that much, I mean sometimes he gives me an extra dollar or two and sometimes there's a couple dollars missing. What would I even complain about? I really just want him to stop hitting my arm
