How did the manager not know Tim didn't have tickets slated for him ? How did Tim not even pick up some (at a lower capacity) and then still helped with the remaining time ?

I guess as someone who does a lot of the same that Tim is doing,and I bet others can resonate, I still "have to" pick up tickets and I think that's always the expectation in any job I've had as an IC. Is Tim managing his time well ?
