You would think that being named Null would probably cause a problem. But Jeffrey? lol

It means "Our incompetence, intransigence, sunk cost fallacy, decision making and hiring idiocy are utterly out of control, and we think this is your problem, not ours. Sorry for the inconvenience."

They used names as the primary key which means Jeffrey is already taken and I guess they can't use Jeffrey2 because it looks unprofessional.

Fortunately, his name is Yeff.
