On my business trips to Paris, nobody refrained from drinking because I don't drink. I would have been mortified if they had. How strong is the "we don't drink if someone doesn't drink" culture? Is it related to social drinking as opposed to, say, having a glass of wine with dinner? I'm just trying to understand the culture and how I can expect my not drinking to impact relations there.
