Oh I could go on for days about working the drive-thru. But wendy's never did make me pay for customer screw ups.
The most annoying thing was that you had to have a manager authorization for every voided item. It's pretty common for customers to say 'You know what, forget the frosty, I'll get a chili instead' only to end up changing back and getting the frosty anyway.
Then you had the assholes who would get mad at me because I don't hable espanol. Not my problem dickweeds.
Then my boss was a downright b****. Terrible attitude, inconsistent application of rules, etc. I was in high school and working 40 hours a week, no breaks, even for meals etc.
I was less than courteous to her when I quit that job(wasn't counting on her for a reference anyway).
