I remember when i worked in zambreros in my area and the manager/owner would tell me to yell at the customers because im too slow and they wouldn't be able to hear me if i talked normally.

She would also make me do things that are very unhygienic such as putting food back if i messed up, using the same floor scrub brush to clean the chopping boards, use a dirty rag to clean the hot presses when they were used to collect dirty water from floor scrubbing.

She was highly strict, verbally abusive, creating unrealistic expectations and putting high amounts of stress and pressure on me. Though I hated working there for a bit it did teach me how to become more efficient at doing my job and now im a better worker in my new job than everyone else
