All this talk about posh nosh and "clientele" reminded me of a meal out my husband and I had a few years ago.
We were tucking into our meal, when a youngish couple settled in at the table next to us, order a dessert and liqueurs. Then "gentleman then went on at length about the various worldwide "posh " restaurants he had been too...the wonderful meals...his friendships with leading chefs, his extensive wine knowledge to his date, every waiter , the manager and chef...bla,bla bla....
It's turns out this was the third restaurant they had been to that night....he liked to have his favourite courses in a different place......zzzzzzzz
When his bill arrived, he did not look at it just paid up by credit card....and left.
Later when our bill arrived although we had had two courses, pre drinks wine and coffees, our bill was for two desserts and liqueurs.
My husband pointed this out....the waiter said " oh dear, I seem to have got the bills mixed up. I can only apologise for you having to put up with that all night."
The revenge of the Waiter.....mmmmwwwhahah
