I have been kicked out of fancy places dozens of times- and every time they performed the thing by handing me the note on a silver tray. I said I have not asked for a note. The maitre'd would say, yes, you pay the bill and then you go and you are not welcome back. The crime could be laughing (a serious offence), or changing a table without asking the maitre'd to fix the change (forbidden by law), or walking around the restaurant room (a very serious offence), or all of them.
I know what.

Laugh every time after dining and drinking! So then you do not have to pay, ever!
The lady was not smart, but she was tough. She had her professional pride to consider.
I wonder how the girl ever got into Bellevue in the first place.
Women are forbidden to enter the fancy places, unless escorted by gentlemen.
She probably had promised to dine quickly, and not to peek at other tables.
And the maitress'd kept watching- therefore she intervened so quickly.
One time I sat down in an outdoor table of an establishment, in the Old Town. They had the white table cloth even there. First I ordered a Scotch. It started to rain, heavily. So I came inside, the glass of Scotch in hand. The maitre'd was very angry! He forgot to whisper. He said: You go now and never, never come back! This is a civilized facility.
