One of my Experience : It was like 1:10 AM(our store close at 2 AM), i was delivering to one of our favorite apartment building.I parked my Lil Piece of crap(though it gives a decent gas mileage) in my usual spot, the sign that says, "No parking Tow Away Zone". It was actually a new apartment(Apt#15), i heard lots of people giggling voices, saying "Do it","common", "just a minute", "Common You can do it" but i was still waiting in the hall with a fking load of pizzas and one of the girl comes out Topless, stands infront of the door, looks straight down( she didn't looked at me), and says "how much was it"? I said : it's 31.50, she gives me 2 $ 20 bills. Me: "Do u want the change ?" Topless gurl : No, U can keep the change. Me: Thank you, U guys have Great night ! Well she tipped me well but when she stepped out, i was like WHAT THE ......! At the same time i heard guys and gurls Laughing & later i figured out the meaning of those words "Do it", "common You can do it" .
