Last time I quit was a restaurant job. Most of my shifts were "on call", so I didn't actually know until early afternoon whether I'd be working that day. Tips were meh, there was a required tip out, and credit card tips were held until pay day. The final straw was when management sent out an email one day to all staff reminding us that calling out due to being hung over wasn't acceptable. I gave my notice and they didn't schedule me again until my final day.
