is it true that advancement opportunities happen quickly in the fast food industry?
I got a job at McDonald's when I was 18, and was promoted to management a little less than two years later. I only stayed there for another year after that, as there is not much further you can climb unless you are willing to stick around for another 10+ years and hope that the restaurant supervisor retires.
As a crew member, we were entitled to half-price meals, and as a manager, free food, although I generally ate for free before that anyway.
It wasn't really the worst job in the world (certainly more fun than I've always perceived retail to be), but you have to put up with your share of abusive / overly entitled customers, particularly at night, and the 'shiftwork' hours prevent you from having a healthy sleeping pattern. I found similar work with fixed hours, Monday to Friday, upon moving to Sydney and probably wouldn't go back to it unless I couldn't find anything else.
