Apparently there has been a shift in consumer economics that I was unaware had happened. Customers make the concessions, not the restaurant. While getting fast food at a place that shall remain nameless but rhymes with CINDY'S, I asked to pay separately and was told, no - just give xyz amount of change to the other person. Stunned silence ensued.
After we drove away laughing about this mysterious new dichotomy, I looked in the bag holding the food. Not only was the salad I ordered not there, it had been replaced with fries, which thereby cemented my theory that something is amiss in the the F&B industry.
Someone! Anyone! Please teach me the new rules! I want to play, too.
