Working in retail i will often see cute/hot women walking through the store. The problem here is that I'm always busy and have no time to make an impression or get them to notice me. Often times they are also with family or friends. What can i do here to be memorable? something i can say to show interest in the 2 seconds she walks by? anything i can say that wont piss off family, but work my way?

most times its about a second or less of eye contact and I'm more than likely with customers.
