Because they’re lying bastards who do that all the time. I frequently get things marked as delivered at the end of the day but with no package delivered, and then low and behold first thing the next morning there it is. They just don’t want to finish up for the day. This is what happens when you know you pretty much can’t be fired. Sorry, I know this isn’t quite analogous to your situation, I’m just venting because it brought up many bad memories.
