my first flight of the year and something almost approaching DYKWIA - travelling alone with two young kids, in Club Europe - the gate agent doesn’t do the usual “family boarding” call (they often don’t on this route as it’s half the flight travelling with kids) - but they call Group 1 (which includes us) so we gently make our way up to the gate when they call that, past the usual assembled gate loiterers - one of whom just barks “Group 1” fairly aggressively as we go past - to which I just said “yes”, then we board. Turns out he boarded much later anyway, so all very weird as to why he wanted to enforce the groups on BA’s behalf in the first place
