This is absolutely the right call. I worked there for several years in the late 90s/early 2000s, but in the Employment Services Office, which is one of the first buildings you encounter after passing through the employee gate. In-park employees would come into my office before their shift to wait for till slips (games and food service, usually), which they couldn't get until AFTER they were in uniform. You have the option to exchange your uniform for a clean one at the end of the day or the start of it, but neither option was paid. So they wait for their uniforms, wait for their till slips, wait at cash control for their actual cash, and then walk through the park to their assigned spot where they "started working". They used to complain to us all the time, but we were just the pawns of the oppressors. We agreed it sucked out loud, and always did our best to minimize the wait, but when the office was flooded with people there was only so much you could do. I even did a stint in laundry, where the uniforms are exchanged, and that wait could be massive at a big shift change.

I forget which company bought the park from WB, but things went massively downhill at that point. It seemed to suck a lot less when WB was still running the show.
