@purplepadma Horrible when that behaviour ruins others' experiences, especially if effort's been invested psyching up for social stuff.
Were once thoroughly fed up with a similar group whose shouty volume rose even further in line with the number of expensive wines consumed. Asked the lovely passing FoH if we could please move to a table further away from the floor show. They got it, shifted us unfussily & our evening was salvaged. We all breathed a sigh of relief when the group left.
