A peculiarly British instance of (at least potential) special-snowflakery here, I suppose; connected with an especial British oddity. The traditional way things work in British pubs is that one goes up to the bar (installed at waist / arms level), and orders one's drink(s) there. The bar-person fills the glasses as per request; the customer pays the cost of the drink(s) to the bar-person; then takes the drink(s) to their selected spot in the pub.
A spot which a few customers often select, is right at the bar, with their drinks resting on its level top; they spend their time in the pub, drinking actually at the bar -- usually standing up, sometimes sitting on tall stools. This of course makes it a little difficult for customers who want to order drinks -- which most of them will consume at chairs-at-tables elsewhere in the pub -- to reach the edge of the bar to get the drinks from the bar-persons. The whole thing is rather impractical, and to many, a tad annoying; but universally gets a pass as a bit of characterful time-honoured British strangeness. It is almost always negotiated in a good-humoured way: the drinkers at the bar move aside a little, to let the orderers get to where they need, and do their stuff.
A couple of weeks ago I encountered -- for the first time ever, to the best of my recollection -- an "advance" on this practice, which occasioned raised eyebrows on my part. In a quiet country pub, an oldish couple were sitting on high stools at the bar, eating a fairly elaborate cold lunch. It was not a highly extensive bar; perhaps eight or nine feet long, in two halves joining in the middle at a gentle angle. The couple and their meal were occupying one of the halves in its entirety. Admittedly it was late lunchtime, with few customers; my companion and I were able easily to get our drinks at the unoccupied half of the bar.
Perhaps I'm being too hard on these folk in seeing them as could-be SS's: but, two people being established side by side at the bar, with a meal "in sundry parts", made it in this location, all but impossible for them to move aside at all, to let a drink-orderer reach that part of the bar. One had to wonder: what if a large party had suddenly arrived, all wanting to order drinks -- with half the bar, "to be served at", being totally blocked to them? Perhaps the lunching couple would have behaved graciously, and inconvenienced themselves in whatever way would have given the newcomers a fair shot at the whole bar. There is an inclination, though, to suspect that if they had been used to exercising consideration and empathy, they would have thought beforehand of the possible turn of events just described; and would have -- as nearly everyone having a meal in a pub, does -- eaten their lunch at a table. I suppose I should give them the benefit of the doubt; but it is hard not to feel that a traditional oddity by which a degree of inconsiderateness is allowed and consented to, was being taken an unacceptable stage further.
