So on Saturday I was doing a demo at a store that now carries my product, and one of the employees of the store came over and introduced himself. We chatted for about 5 minutes, mostly about me being afraid my car would get towed and the location of my store. So yesterday I get an email from him that it was nice chatting with me and to let him know if I ever want to grab a beer. . . um, what? We talked for literally 5 minutes. Did he just ask me out? What am I supposed to do about this?
