The night. 24 hours shop. I choose between good and expensive beer. A man comes in, not very sober, with a cigarette in his mouth and a dog on the lead (a small one). The guard man:

You cannot go here with a cigarette.

The man with a dim look looks at the guard, blows a cigarette on his tongue and... swallows it. Cool of course, but okay. The guard adds:

Not with dogs either.

I thought the dog was getting very bad.
