Not what I said but how I said it.
Waiting tables and I get this friendly looking couple. I walk up and before I can start with the pleasantries the guy sees me, and in a heavy Australian accent, he says "hi there mate. How are you."
I was thrown off by the accent and by being interrupted before making an introduction and for whatever reason, my mind could only focus on the accent, and so, when I went to respond I did it in an Australian accent -- "not too bad mate. Yourself".
I realized i was doing it as it was leaving my mouth but I couldn't stop. I was convinced I was gonna get pinched square in the face... turns out my fake Australian accent isn't bad. The guy is delighted to meet an Australian. Asks if I'm in America on the Work program.
Now I'm stuck. If I admit I'm not Australian I'm worried he'll be offended even though I didn't mean to offend him. If not, I have to play this part for the next hour.
Yeah. I committed to the role. Got a 40% tip though so that was kinda nice and worth the stress.
