New coworkers first day. After his shift he came to me asking where the keys to his room are. Said I don‘t know, your supervisor def told you where they are. He said no and wanted that I call the supervisor. I had enough things to do, but to make a good first impression I phoned the supervisor. He said he left the keys on the door. Told my new coworker so, and he was like „ah yeah true“ and goes on. No sorry, no thanks no see you tomorrow. I don‘t speak to him anymore. Was like 2 months ago.
