Wedding is being paid for by my parents/ future husband and I. My fiance brought up at dinner with his parents, very awkwardly and without warning me, about what they were going to offer to pay for (they hadn't offered anything yet, I wasn't too worried about it, I want a low key wedding anyway).
Fiance's mother states that they will NOT pay for any alcohol since his dad once had a drinking problem. I'm totally fine with that, fiance and I don't really drink but we will have alcoholic beverages for the wedding guests.
Come to find out at a recent wedding, both his mother and father drank at the reception. I'd seen them drink at family events so I wasn't surprised, but Fiance has an issue with it. Fiance is now upset and doesn't want them drinking if they are refusing to pay for it on moral standards. I REALLY don't want this to become an issue, what do you guys think? Leave it alone and risk Fiance getting upset and saying something at the reception. Talk to them in advance? What do I say?
