Okay, so I work at a supermarket, deli to be precise. But I'm checkout trained. Yesterday I was called into work at the checkout for five hours and since it was Friday, it was really quiet. I was working with this guy and he's so cute and we just kept talking and talking and we got along soooo well! I even thought that maybe he might be interested? But maybe he was being nice. I just keep thinking about him but I don't think we're ever going to talk again. Because it's a big store and we work in different departments. Can anyone give me advice? I was thinking of getting his Facebook but would that be weird? Help me pleaseeee! xoxoxx
