I was working at a mcdonalds drive through a few years ago taking orders and money when my friend dumped a handful of ice down my tucked in shirt. I was in the middle of an order so I couldn't do much about it and the ice just sat there at my lower back.

I hurry and finish this lady's order, reach up to turn off my speaker, and yell at my friend, "you fucking cunt". Immediately I realized my mistake. To my horror, the speaker was still on and I just called a sweet old lady a fucking cunt over the speaker.

I was sure I was fired, but after she got to my window and I profusely apologized to this lady she just drove off looking very confused as to what just happened.
