Subway complaint: Manager

I was walking to the subway and was almost hit by a car in the parking lot and was angry about that so I walked into the store I told the gentleman who is driving to watch out you almost ran me over I told the gentleman he says all calm down and I did at the same time the manager was giving up the food and overheard the conversation, I ordered my food which was a turkey sub on a multi grain bun 6 inches and he had a cut a little piece of the corner of a sandwich in the refrigerator when she took out because when he took out the next one for the next customer was twice the size. I mentioned why did you give me such a little piece of bread when hers is much bigger and he says oh throw out of the store because I made a complaint about the sandwich and I almost had myself ran over by a car so I was angry about that I would like that man to be discharge from his job very rude
