AITA for taking a shit on the front counter of a Burger King?

Title sounds bad I know but hear me out.

I (M19) went to Burger King with my girlfriend (F72) for lunch yesterday. I ordered a Whopper meal with no tomato.
When we sat down to eat I bit into it and tasted the disgusting fucking shit that is tomato.

I went back up and pushed my way through the line to get to the cashier. I knocked over a woman and her two kids. The cashier was probably like 16 and he tried being a smart ass with me by saying “I’m very sorry we can replace your meal with a new one”. He even smiled at me when he said it.

I’ve been trying to control my anger lately but I just snapped at him because of his sheer fucking ruthless disregard for the slogan “the customer is always right”.

I climbed on the counter and pulled my pants down and took a nasty shit that landed all over the cash register. There were audible shocks around the store. I then lost my balance while squatting and feel backwards landing on my back with my bare ass hanging out.

I heard some fucker scream “this muthafucka just shit on the counter” I then was grabbed by police while trying to stand up.

One of the kids I knocked over broke her elbow and I’m being charged with assault and indecent exposure among other things. My wife has cancer though. AITA?
