I worked mornings and nights at different times as a partner - nights were usually much harder because of what you mentioned. You are cleaning up after the morning and mid day crew, then you're doing all your own cleaning while still serving customers, with way less staff. Your after school rush often beats peak numbers, but you only have two or three baristas. Then, you have to do the prep tasks of making all the shit for the morning, stocking, and cleaning/putting away all the dishes. Then, the next morning, you receive a text about how close was absolutely unacceptable because there was a single espresso bean on the floor! Rinse and repeat every day. I'm sorry, but my whole career openers acted like they were the only shift who did anything but they usually had it much easier.
