Two Cousins Pizza & Italian Restaurant

After 15 minutes waiting for my sub the woman behind the counter asks me if I ordered a cheese sub. I said yes. She says she thought so but the people in the back made the wrong sub. In another 5 minutes she comes out with my order. They offer me the mistake sub for free but it has meat in it so I said no thanks. I go out to the car and check the sub, there's no mayo. I go back in and say there's no mayo. The woman says I didn't order mayo. I assure her I did. I tell her that I think that sub has oil and I don't eat oil so I assume they will make me a new sub. She comes out in about 30 seconds with the same sub with mayo thrown on it. The woman was rude and the service was horrible. I understand that mistakes happen, but I was the only customer in the place.
