I offered a cop some beer

How? 

Well... I was with my boyfriend and a friend outside drinking and starting a small fire pit to stay warm. We had a great time and we got really drunk drunk. We live in Germany by the way and in Germany it's illegal to just make a camp fire in the woods near the town.

 A few hours later cops were called for a few men fighting nearby. They noticed us because of the music and the fire. The cops walked up to us. It was dark and I thought they were some friends of my friends and I greeted them all excited and offered them beer, which they politely denied and I was like: "cmon man it's Friday". They told us to put out the fire and that they wouldn't charge us and my dumbass realized they were cops when they turned around to leave.
