I hope I was right to walk out.

I got a job a couple of evenings a week at Macdonalds, but on my first shift all I got from the guy who was shadowing and supposed to be teaching me was how bad it was to work there and why anyone would want to work there is a mystery.
I got this the whole evening with little to no training so called and said I wasn't coming back
My mum is happy and said if I don't like it then fair enough and maybe to try for a for a more mixed ages job where I can get trained properly.
I didn't want to report the guy and get him in trouble.
I feel a bit bad now but I guess I will be easily replaced.
