I'm afraid I don't like gender inclusive language. Much like you with the word 'queue', I find gender inclusive language unnatural and a silly affectation :))
To get back to London, it is one of the few really
diverse places in the world. It's a fascinating place, filled with 'characters'. When I lived there I used to go into a little cafe in Notting Hill Gate. It was run by a Greek and was exactly like your granny's dining room, floral carpet, lace curtains,white damask table cloths, real home-made gravy contrasting weirdly with tinned
potatoes! The customers were such an interesting mix. One was an elderly Sir Somebody-Or-Other, there was an old lady who used to slip sugar lumps into her handbag,then there was a Spanish guy who ran a boutique nearby who used to come in with his girlfriend, he was about 40 and she was about 20. And there were two young guys who busked nearby and dressed in 1930s garb, suits, overcoats, Trilby hats, the whole lot. The waitress treated them like her own sons. Once they got up and gave an impromptu performance of 'Underneath The Arches' by Flannagan and Allen.
Then there was another place on the Finchley Road, Italian owners, greasy spoon 'caff'. Customers were builders, bikers, truck drivers, office workers and the girls from the ballet school nearby, with a few old tramps and homeless guys who would sit there for hours on rainy days nursing their cups of tea and chatting with the owner.
