I'm having a hard time gathering the courage to ask this guy

Hey Reddit!So the past few months I've been frequenting a Subway near my work at least twice a week for two reasons: I can't get enough of my BLTs and one of the employees.Ever since I first saw this guy working there I was interested by him. Since I started going more often, I'd see him there more to the point that I started to develop a crush on this guy. I had told one of my coworkers about him and she just happened to go to Subway one day with me and had finally see what I had talked about and concluded that he was interested in me, even though I was trying to figure out if he was and wasn't having any luck.Since then I've still been going, every time almost asking him for his number or maybe compliment him in a flirty way and see if he would do the same back but I can't bring myself to do it. I'm a little afraid of being denied, but it's mainly that I don't want it to make it awkward because I frequent this place so much and I actually do like the food. I go so often that he started to remember my order, and my coworkers think its because he's interested in me but I just think it's because I go so often that he started to remember my order.I'm still trying to think how I could go about asking this guy, and I want to believe he's interested but I'm just trying to think of reasons why he couldn't be.
