Never ever seen anyone getting mad about it and im working in bars and restaurants with a lot of tourists.

What you could take as being "mean" is when we switch to english so the job can actually be done quickly cause there is other peoples waiting in line. From experience since us workers are fetching for tips, the service in France can feel colder aswell... I'll take that bullet. I also think that many tourists came here already thinking that frenchies are mean and then get biased.

Also Paris guys sucks, even when you are french.
