There were five cars in front of me in the drive-thru, and I hesitated to stop because I thought that line was doomed to be a dreadful 10-20 minute wait. But the line made space for me seconds later, as if it read my mind. I was handed my food three minutes later (if even), greeted with apologies for what only a total arsehole would call an unreasonable delay, AND my order of fries was upgraded to the next size up as an olive branch. My order was filled perfectly, and, having finished my entire meal comfortably at home 20 minutes later, I feel like I should have generously tipped.
My point is that I get the feeling the employees are being worked like race horses which is not healthy. There's no reason why people should feel the need to apologize for doing their jobs really quickly and without mistakes. I can't imagine they're getting paid enough for that.
Thanks, Jack-In-The-Box crew around the time I wrote this! You're doing more than well and can totally afford to relax just a bit.
