Lurker, first time posting here.

So I'm working in a different town for the week and I forgot to pack my sunnies. They're almost a necessity where Im working at the moment because its hot as balls and its super bright outside (Northern queensland, Australia). No problem, Ill just pop into the local surf store and buy a pair. So after I settle on something that looks semi-decent i take them to the counter to buy them.

While the purchase is taking place the girl serving me is making eye contact, small talk and smiling (IOIs?). Maybe she was just being nice to "the customer" or maybe she was actually interested. I'm not sure.

Should I go back? And if so, how to I approach when she's at work? Im semi-confident with approach at bars and in public but I'm not sure about someone who is at work.

Im probably going to go back if no one replies by the time i finish work today (in like an hour).

Update: went back, she had gone home. Oh well. Might have a check tomorrow :)
