People need to be studied by NASA. Something similar has happened to me. The difference was that I needed to scan a client's document to insert it into the work system. Then I had to take a copy of the ID and attach it to the registration form. When he saw me taking the copy, he asked if I could take another one for him. As I was already doing it, I took the copy and gave it to him. After half an hour he came back swearing at me because, according to him, I'd handed him a copy of my ID that was dirty with poor water.
