I work at a hotel. The hotel has a bar. At about 2:30 in the morning, this guy comes in and tries to buy a beer before going to bed, but I explain alcohol sales cut off at 2 in this state.

He didn't like it, but he nodded. I check him in and he walks away

Suddenly I hear a noise like an out of control fire extinguisher. I step around the corner to find the idiot has gone behind the car counter, grabbed a pint glass from the shelf, and tried to serve himself a beer from the tap. What he didn't know is that there's a lil plug that gets inserted into each tap before the bartender leaves. He's soaked in beer and there's the tiniest bit of foam in the glass. I took a picture of him on my phone, called the police, and told them I had someone here I needed removed from the property.

He tried to go to his room, so I sent the cops there for him.

All in all a good time.
