This customer was by no means sucky at all. He was actually cool as a matter of fact.
He comes up to my register and pays with a check. He pulls out his ID, and his first name says "Evil".
Surely I thought nobody would be so stupid enough as to name their son or daughter that. He had a work shirt on with his name imprinted on it, and it said "Elvis". I told him that they probably misspelled his name on his DL, and he tells me that Elvis is his nickname. Evil is actually his real first name, it was not short for anything according to him.
God, I would hate my parents forever going through life with a name like that. I wanted to ask him more, but thought the better of it so I wouldn't offend him.
