In college I worked for the owner of an Ice Cream shop. I got the job because a buddy of mine was the shift manager or some other bs, I can't remember. I came in early on certain days because most that worked there were high school kids not allowed in the freezer and that dropped off deliveries.
My buddy was a good looking guy and could do no wrong, he would stand in the blind spot of the camera's in the place and make out with another girl that worked there (intentionally) while I was left to fend for myself with the customers. Meanwhile the owner would spend hours watching the camera tapes, take notes and chew me out for every time I leaned or stopped working or did anything wrong.
She was a penny pincer to the point where I'm almost 100% sure health code violations were broken. We had little tasting spoons for different kinds of ice cream for people to try before they invested in an entire scoop. She would actually have us re-collect those, rewash and reuse them.
Also when we laid out all the blenders and ice cream scoops and stuff at the end of the night to dry we would re-use the same paper towels every night to save money. If you used "Fresh" paper towels you'd better have a good reason. And then in the morning roll up and carefully put the paper towels back. God forbid you ripped one....
One time we thought we were out of milk so I got sent to get more while she was out and when she came apparently we still had some. I got ripped up one side and down another. I wish she would have just fired me on the spot.
I also got yelled at for giving customers both too much and too little ice cream.
Another time I got yelled at when she sent me herself to get more banana's for banana splits, I got ripped for buying the "expensive" kind.
Another thing we did (only when she was physically there) was she had us charge people 25 cents per dixie cup of water. I know it was her business but it sucked having to look people in eye and tell them that.
The way I got out of it was summer eventually ended, although I said I had to go back to school a lot earlier than I really did.
All that for 4.25 an hour.
