People have really funny ideas about restaurants. Somebody once left an online review of my family's establishment complaining that the hot chicken that was supposed to be on their cold to-go salad was in a separate container. They asserted that it was a "trick" to keep the chicken warm and moist, as though it would have been better to let the hot poultry heat their salad in the same container until it was lukewarm meat on top of wilted greens. Every day I wake up and mourn the IQ point that I lost reading it.
