Unprofessional. Owner cursed me because I asked one of his employees to mention for him to wear a mask as he didn't have one on. Staff proceeded to talk about me as I was leaving. Also. I was called for an interview a few weeks ago to come in today. I called yesterday to confirm again. When I sat down earlier today to interview. The position wasn't available. No explanation as to what happened.
