In a situation where there is no line of people, but people are arriving and milling around before, say, a bus arrives or something opens, are you able to read unspoken signals about who should go first?
I have no clue about this sort of thing and prefer an obvious line of people, ticketing system or whatever.
(this question is inspired by an AIBU thread about a 'bus pusher-in' but isn't intended to be a TAAT about that individual situation).
If it's not a 'silent language' you can understand, how do you deal with those situations?
I would just walk forward 'as it happened' and hope for the best but I am possibly causing mortal offence to NT people who are following a system to which I am oblivious.
