Have been going to this restaurant for a while, the last time I was there, he made a drink for me and let me name it. He is really cute and nice, but I'm not used to being forward and usually let the guy come to me. He could be just being extra friendly for the tip and I thought of just casually asking him, if he wanted to make me a drink after work, but trying to be careful because if he is dating someone or is not at all interested in me, it will be weird when I go back in there for lunch or drinks. What should I do??? Any ideas? Thanks.
