Not OP, but a happy hour is usually a period of time when bars serve discounted drinks and such.

It's illegal in several States. It was only made legal here a couple of years ago.

>The reason for each ban varies, but include: to prevent drunk driving, avoid the nuisance to neighbors from loud crowds and public drunkenness, and to discourage unhealthy consumption of a large amount of alcohol in a short time.
