So I work as a cashier at a Forever21 store, lots (and I do mean LOTS) of beautiful girls coming in. Some of them show indicators of interest, but I usually only have about 30 seconds of time to talk to them...

How can I manage to get some of their numbers without being so creepy in such a small amount of time? Feels too short time to establish authentic connection, Keep in mind I’m at work & boss often behind me
