Pros
Pilot Flying J is a large corporation that takes wages, hours, and business operation seriously . Although they are primarily a minimum wage corporation, at least for the restaurant in Pilot Flying J for which I work, I hear cashiers for the store side are paid better. It's probably nicer and less stressful over on the store side as well, although you have a constant influx of customers. My experience must not be much different from a stand-alone restaurant, although there is the occasional interaction between us on the restaurant side and those on the store side. Overall, it is a job, and there are much worse places to work.
Cons
They are heavy on suggestive selling, making it feel like you've always got to pester every customer for every penny, instead of allowing you to really focus on the one true thing that matters - SERVING THE CUSTOMER! The one thing about Pilot is that they are money-Mizars; you will not ever get overtime, and there have been many occasions we just did not have enough employees to handle business.
