I'm kinda curious about something I've noticed on WW. Sometimes, when a bride asks about something controversial like a cash bar or asking for cash instead of a registry, other brides warn her that it will seriously offend her guests. I don't understand this at all. I mean, presumably a guest cares about the bride and groom, so how can they get honestly offended over something as seemingly minor as a gift preference? I know etiquette is important to some people, but to me, it seems like bad etiquette on the guests' part to get upset at someone who's inviting them to a party, giving them free food, and trying to share their special day with them.
I really don't mean to offend anything by asking this. I've seen many people say this is a regional or cultural thing, but it doesn't make sense to me, personally, so I figured I might be able to understand it better if I just asked. So yeah, I'm just curious, not trying to cause drama.
