A norwegian easter eve joke

Actually it's not a joke, because it's not funny, just in case your expectations got high.
And it's not norwegian either, I just made it up, but lets pretend it happens in Norway.

- A portuguese guy walks into a supermarket and asks for a beer.
- The clerk says: no, sorry, it's already past 3pm.

See, I told you it was not funny. Not at all.
