I was drinking a beer at a place in DC and a dude came in, clearly freaking out. He was sitting next to me asking the waitress questions while he was sweating his ass off. He then went to the bathroom and I told the waitress to give me a knife. When he got out, he sat next to me and I sat the knife down with my hand over it and asked him if he really wanted to do this. He freaked and ran out. If he would have gone for the waitress, I would have bleed him.
