Relationships

This guy is putting the ball in my court. Why would he do that? Please help!

Okay I need some opinions fellas. There is this guy I really like who works at this store I shop at. I've known the guy for a while and he's started to get to know me for the last couple of months and we've been having long discussions every time I visit. I find out he does glassblowing and that he's really passionate about it. So last week I asked him to make a pair of earrings. I also asked how much he charged for them. he says 40 but he'll charge me 30. I figured hey that's nice of him. He asks for my number and he'd give me a call when they're ready. A few days later we arrange to meet up at the coffee shop. I get the earrings and we chatted for about 20 minutes (just so you know this is the first time we meet up outside his work) and he mentions his friend was waiting in the car and had to give him a ride. He apologizes and didn't want to leave so he says we should actually do coffee sometime this week. I tell him I'd like that a lot. So he then says I should give him a call when I'm free to meet up. I figured that was odd, why couldn't he just call me? I plan on calling him this weekend to set something up but at the same time I feel he's not that interested since he put the ball in my court. Could he be just nervous? Or is this a bad sign?
