Should I visit a guy at work?

So there's this guy I've been talking to. Several months ago we went on a date and he did ask me to hangout again afterwards but te problem was I moved away to college and wasn't around very much. Recently we've been talking again since I'm back home for summer and he has invited me to come over and hangout, but once again the times haven't worked out since I have a summer job. I mean I think this guy is really interested, he tells me I'm pretty and a few days ago when I went to te movies with some friends he asked me who went, I guess becuase he wanted to know if I was there on a date with another guy, which I wasn't. He also did come by my work a couple of days ago ad mentioned he had also come in the day before and though he would see me (I wasn't working that day). I work at a pharmacy store like Walgreens so it's not a store peope just go in everyday. That night he asked me if I wanted to hangout but becuase I had to work late I said no. I asked him if he wanted me go come visit him at work tomorrow and he just said do whatever you want, which is a weird response. I don't know if he was just trying to sound cool and not sound excited. Should I do? I'm a shy person in general and I'm nervous about going in te store he works at. I was thinking I would go before my college class starts. So I can see him for a few minutes and if things are awkward I can say I have to leave to get to class on time.
