Man is a child of nature and the freedom of choice is its natural need and condition. However, when it comes to nutrition limit the choice of location for its implementation to the borders of your home and if you need to be away from home for a short time (on an excursion for example) carry a homemade meal.
As you noticed in the course of the TV show "Nightmares in the kitchen" with chef Manchev catering establishments are unhygienic and poorly maintained as therein is an usual practice to be reheated cooked meals prepared 2-3 weeks ago into which are placed god knows what kind of "quality" products served in "excellently" washed dishes stored in the same "sparklingly clean" kitchens. Precisely this is the reason why I myself have always avoided eating outside my home but now after watching the TV show in question I will never ever again hesitate even for a second whether to undergo such self-abasement and neglect my own health.
