re: People who return their food everywhere they eat

Only times I've ever sent something back in my entire life was the 2/3 occasions where I ordered a med rare steak and it came out well done. Every time I was as nice as possible and each time the chef came out to talk to me and apologize because it was at a place we have frequented for 20 years. Treat people with respect and they will generally treat you with respect. Sending a dish back because it has an issue isn't a problem. Sending a dish back and being an a-hole about it is.
