Not to derail your thread, but awhile ago I saw a dude bump into a guy while he was getting piping hot water at a convenience store to make tea.
The guy who did the bumping is all tatted-up, looks like a Mexican Mafia wannabe. He's a real burly dude, built like a brick shit house, but mostly overweight. Walks to the end of the line (there were only two people ahead of him), but had to walk between the person in front of him and another guy behind him who is trying to make tea at the coffee station (with his back to the line). Burly dude just brushes into the guy making tea and causes the guy to spill hot water on his hand.
The guy who got burned says "AHHH...shit!" while pulling his hand back and slinging the water off. He looks at the dude who bumped him and the guy just ignores him. Burned dude says "Hey...I got hot water here." The dude looks at him with an expressionless look on his face and replies "Yeah" as if to say 'OK, whatever.'
Burned guy looks at me, I'm looking at him shaking my head as if to say 'what the fuck is his major malfunction?' He turns around to the guy and says "Yeah? You made me spill boiling hot water on my hand...and all you can say is "Yeah?"
The dude says again, "Yeah" this time even more crass than the first and then turns away (toward the line). The burned guy gets red in the face and I seriously thought he was going to retaliate. I'm thinking to myself, if this gets ugly, and I have to punch this big fucker in the face, its probably going to break my hand while not phasing him too much (he had a huge cow head). So then I start sizing up where I can hit or kick this big fucker for most effect (I settle on a hard side or stomp kick to the lateral knee or tibia).
But burned dude just says "Watch what the fuck you're doing next time." That was it. Burned dude finishes making his tea (you could tell he was furious) and there are no more words exchanged. Burly dude gets to the front, pays for his stuff and walks out.
