At a car dealer:
“Are you guys going to buy that car or what? Because if you’re not I’m gonna walk right out that door and sell it to another couple that’s looking at the car within 30 seconds.”
And he did.
At a tattoo parlor after a customer just left following a somewhat painful experience:
“Sometimes you make them hurt so they don’t come back.”
I’m told the other tattoo artists in the room all gave an evil laugh.
