Quick flirting??

the other day i saw this really hot guy who worked at the movie theaters, he was working at the consession stand so i decided to go in his line and buy something, i wanted to say something to him so i could get my point across but i couldnt think of anything and ppl were waiting in line behind me so i couldnt exactly stand there and chit chat yakno? well for future references, what kind of things could i say in these situations to get my point across???
