Worst job I ever had was as a dishwasher at a resort in Muskoka.
The kitchen was absolutely filthy, the chefs were mean, and I was 15 years old.
Quit after two days, and ended up spending the next week (and following three summers) as a dishwasher for a rival Muskoka resort. Much nicer work space, great chefs, they even cooked meals for me since, let's face it, who brings a packed lunch to a restaurant? Good times.
Funnily enough, two years later one of the chefs from the first resort, eventually ended up working in the kitchen I had moved to.
He remembered me, too. I don't think he was happy that I quit on such short notice...but whatever, **** that guy I made my choice and I stand by it.
