This guy at work gave me money to buy one of our coworkers something because he was too lazy to get himself and "he had no money". When I came back for our co-worker I gave the guy the money and he was like oh there's a dollar missing but I counted it before I gave it back to him so I knew he was kidding . He then touched my thighs or where my pockets would be to "search me". And then he liked joked that I owed him. He touched my face and then left to go talk to some other people .Later that day when I was sitting with a friend he came over to say hi to him and then people around us and then sat between me and my friend. He sat so close that like our knees where touching. I kinda looked at his knee and then him but didn't move . When I looked up at him he was kinda smiling but looked like he might have been testing me.
