Have you ever cursed someone out/been cursed out?

I was onced cursed out by a very old woman at a grocery store, she hit me with her cart and said move f*ck*r! She was behind me in line. not kidding, mabe somthing was wrong with her. When she did this at first I grabed her cart and shoved it back at her, I didnt know it was an old lady it was just a reaction, she then called me an SOB! and then the cashier screamed to cut it out. It was just wierd.
