You should see some of these wackjobs that come in here. Just the other I had this guy bring in his pool cleaner. He said it won't move. I look at it and notice the tire is hanging off of it and it is preventing the cleaner to touch his pool surface.
I picked up the tire and held it to his face and said, "See this?"
He said "Yeah, so?"
Me: "It's called a tire, and it belongs on that wheel."
Him: "Can you fix it?"
Me: "Sure, but I'm going to have to charge you $10 in labor, OK?"
Him: "OK, this stuff is too complicated for me."
I slid the tire back over the wheel, it was fixed!
Him: "WOW! Did you have to goto school to learn how to do that?"
Me: "Nope, I watched a video and used common sense."
Him: "You're so good!"
He paid and left.
