It's not really bad but still makes me chuckle thinking back. My first job in highschool was at a fast food franchise in a very small town where you would know many of the people that came through.
Whenever a girl came through that this particular female coworker didn't like she would do whatever she could to increase the caloric count of the order. If the item had mayo she'd say put extra mayo. If the order had fries, put extra fries, larger soda/ice cream, extra cheese, etc in an attempt to make them just as little bit fatter out of spite - it was hilarious to witness this ritual.
Cindy, if you're out there I hope you're doing well.
