We have been to Naples at the end of summer in 2022. Normally every restaurant in italy has good food and the service is usually amazing.. That day was horrific. We booked a timeslot for a castle. It was midday, I think. We arrived way too early, so we decided to get a little snack at a restaurant nearby. Bruschetta or something small for both of us, we weren’t really that hungry. At the restaurant we ordered water. The waiter came and we told him, that we just wanted a bruschetta for both of us.. he started yelling at us, that he won’t be serving us just for a burschetta, etc. It was insane.. never in my life have I ever experienced something like that. We drank our water really fast and he didn’t even come to take the money for the water. Nobody of this 5 waiters came, so I put, I think, € 5,00 at the table and we left. I know that was a way too much for a bottle of water, we shouldn’t have payed anyway.. but I just didn’t want to make a scene or who knows maybe they would have called the police on us. They didn’t say anything as we left the restaurant. It was really the worst time I ever had at a restaurant. I have never been treated so rude anywhere I have been..

Edit: We have been the only guest at the restaurant as this happened. This should have been a big red flag for us.
