A blonde walks up to a coke machine in Vegas. She puts in some quarters, out pops a coke, she puts is some more quarters. She keeps doing this, time and time again. Eventually a man comes up behind her and wants to use the machine. He waits patiently for a while and then finally taps her on the shoulder. "Excuse me Miss, can I use the machine?" The blonde turns around and says, "Fuck off, can't you see I'm winning?!"
