I'm not sure how to approach him and make small talk or ask a question without seeming weird or like I'm coming on too strong. I want to stop by and say hi to him once a week, but he works at a part of the store that a weekly shopper wouldn't need to visit that often. I do see him walking around sometimes, so would that be a good time to approach him if he's not too busy?
What do I say to him? How can I tell if he likes me? Would it be okay to give him a piece of paper with my number on it after talking to him a few times?
