I can't even begin to describe the good feeling you get, after being a professional, when someone even cooks for you.... It can be as simple as Mac & Cheese. Just the fact that some one cooked you a meal and that you got to sit down (not standing on the fly) and truly get enjoy it at an appropriate temperature is a huge thing. Something that becomes so important and not taken for granted. Some one actually cooked for you!...
The host or hostess is all nervous about whether or not you are going to like it and that is up to your standards.. When in reality, you rarely get a hot, cooked for you meal done for you!...
It brings into the picture a sincere appreciation for foods prepared by some one else.
