To be honest, my sleep schedule is still pretty messed up, even years later. I worked retail and as a server and had to do close into open shifts all the fucking time. Sometimes even close into working a double. It's fucking insane how they expect you to work 8-10 hours, leave the restaurant/store at 11 pm – midnight, then be back at 9 am the next morning.
I always used to hang with bartenders and other servers. Everyone hung out from like midnight to 3 or 4 am because it's the only time where our friends were available. The only free time we had to ourselves was late night and early morning. I just think it's fucking crazy how normal it is to work someone like that. It happened so often and even thinking back on it I get tired just remembering morning shift after 3 or 4 hours of sleep.
Fuck that shit.
