You would get awful reviews if you weren't doing a good job of it, but aside from that, why would anyone really be offended?
If you guys were coherent, places like Olive Garden should never exist. And I am not even starting on how much of a shit job Olive Garden is doing of trying to look Italian, because I don't care.
Europe, with such a rich mix of cultures should be a trigger-hell for you Americans.
(I am being sarcastic) How can you really cope with all this?
Edit: to add insult to injury, how should we Italians feel about being always portrayed as "pizza, mafia, gobbledygook mamma mia". It's so far from our reality, we don't care.
Edit2: better phrasing
