worst job - Retail Sales Associate Goodwill Employee Review

I was hired full time and never once was trained to work the cash register the entire time I worked there. I spent my entire 9 hour shift hanging up clothes. Granted I did quit after 3 weeks but I have never not been trained to work the register within my first few shifts. The pay was terrible. As a full time employee I only got paid $400 every 2 weeks. I was young and very dumb.
