This topic always gets lots of views and emotions when it's posted. I would suggest this is one issue that could be factually summarized and saved as an FAQ which would save a lot of frustration.

For us, after a couple bad experiences, we rarely eat on the French side now because of the uncertainty of proper tipping practice and etiquette as well as questionable restaurant ethics as mentioned above. As we all know, there's some great food to enjoy and that's what I want to do, rather than spending time figuring out what each restaurant's practices really are so I can tip properly and not be taken advantage of.
