the only somewhat bad experience ive had was when I went to a restaurant and asked for the panzeroti without meat (since im a vegetarian) and the waitress said they could do that. So I get the panzeroti and start eating it, but it smells like meat. Not really thinking anything of it, I dig further and find it was filled to the brim with meat

so I asked for a new one and the waitress was super apologetic, and then the next one I got had no meat in it, but was burnt on the edges and cold on the inside since they rushed the cooking to get it to me so I wouldnt complain.
First world problems

I still eat at that restaurant though since its really good
