When I still worked there, rush time was quite stressful and fast-paced. Depending on how many people were on shift during the time, my manager would have me running from oven to register, preparation to being dishwasher.
Some days I was even alone during morning shifts, my manager would've gone to the bank while someone else would be dough rolling in the back, but I would be managing everything during those times.
The hardest part of the job was my coworkers, several of them were nice and I became friends with them after work. Many of them, however, especially the new people, would laze around and even pretend to be doing something even if they could plainly see we were backed up on orders.
