Seems some rational thinking could have solved this one straight off.
Thug: "Hey, come over here for a minute"
Me: "Sorry, I can't do that."
Thug: "Hey, where is the local tattoo place?"
Me:" "I don't have a clue, have a good night."
Thug: "Ok, but can you come over here for a minute?"
Me: "Have a good night."
Anything he says after that I'm basically not going to respond to. I'm not going to stop what I am doing to fidget with this guy. If he wants to keep yacking that's fine, as long as he stays over there. I hope I don't offend him when I drive away when he's mid-sentence.
