I was out walking the other day and noticed a bunch of young workmen going into a pub after work. They were in their work clothes, but one in particular was really grubby. His jeans covered in grease and dirt.
I realize they were going to a pub, but same pub's clientele gets a bit fancier dressed later on, and many office workers go there for lunch. Some of the seats are padded vinyl, the ones up against the wall are upholstered in cloth.
What do you thing the protocol for this would be from the server's point of view? Direct him to the vinyl seats, give him a newspaper to sit on, refuse him entry? I know I wouldn't want to sit in the seat after he had been there.
