There's a lot more to this than just the fact he's lying about his age. He has asked out almost every woman and girl at my workplace. He is taking girls personal numbers from the work groupchat to ask them out on dates etc even if they haven't had a shift together. He is lying about his age to everyone. He's even telling minors (16/17 year olds) that he is 20 before asking them out etc. He's made so many people uncomfortable at my workplace to the point they don't even want to come in.
