No matter how I parse it I can't make this sign, seen outside a town pub, make sense.

No hoods
No ID
NO SERVICE

Do the want people with hoods AND/OR ID?
DO they not want people with hoods AND/OR ID?

????

I don't think they want anybody's custom.

Sans service, it must be self-service. Not a bad thing in a pub.

Maybe they don't want hoodlums ("hoods").

I know what the "hoods" means. It means nobody wearing hooded sweatshirts (hoodies) widely seen here as the mark of thugs and hooligans.
What puzzles me is the idea of NOT being served if you don't wear one, which I'm sure is not the intent of the owners. (Mind you it's a pretty low dive, so maybe...)

NO shsirt (If you're not wearing one)
No shoes (If you aren't wearing them)
No Service (We won't serve you)

No hoods (You can't wear them)
No ID (You must have some)
No Service (We reserve the right to avoid parallel construction)

I think Proof's got it right. It just needs a semicolon after "hoods."

We reserve the right to avoid parallel construction.

I love it.

Does anyone know if hooded sweatshirts are considered "thuggy" here? I wear them. I guess I'd be kicked out of that pretty low dive...
