What are some good tips to remember when eating at dodgy eateries?

Invariably you will find yourself in some interesting places as you travel. Whether by sheer economics, desperation, or worse yet, the counsel of a trusted friend you will wind up in a compromising position from time to time. In general it’s best to heed a few simple but effective pieces of advice:

1. Never eat raw meat or fish. This includes unwashed fruits and vegetables too.
2. Avoid precooked hot foods which contain meat, fish, egg, or dairy products that have sat “for a while” under a heat lamp or unrefrigerated in a window.
3. If the local tap water is deemed unfit to drink (unpotable), avoid drinks containing ice or other beverages that haven’t been boiled or bottled in origin.
