I prefer full disclosure when there is/are extra charge(s). When we are asked if we want something extra, I ask if there will be an extra charge for the extras. If I see an extra charge on the bill, I ask them to remove it. I DISLIKE when they suggest add-ons that are extra charges.

We may give an appearance of being "cheapskakes" but we would like to make informed choices concerning extras.

We were in Lisbon a few years ago and we got charged for the meat/cheese plate they put on the table. Since the meal was very reasonably priced inside a very large Lisbon mall, a few extra euros for the extra was a very valuable lesson learned. (glad we were not in Rome where they charge more than a few euros for bread!!).

Bottom line: We always ask what extra charges are for the suggested extras. What are the prices of the daily specials the waiter/waitress suggests for our meal. We find they do not mention the prices of the daily specials! The daily specials are much expensive and usually not to our liking!
