reminds me of one sign in front of a bar in Tampere, which is what we call "student city"; there are two, maybe three Tertiary degree schools there.

The sign said "no overall people", ie. people wearing student overalls which seem to have super powers of their own; when you wear one, all common sense disappears and is magically replaced by bottomless thirst for alcohol. We are loud, drink a lot, and ma (or rather, WILL) do dump stuff, but won't start fighting or breaking anything.

Yes, I am in fact one of the overall people.
