What's a common tourist activity that happens in your country that you feel like is a scam?

For me I feel like when people come to my country (Tanzania) to try local foods i think they are being ripped off really badly by many tourist restaurants/hot-spots

Meals that usually cost me less than 1 dollar to eat at a local place would cost 10-15 usd in a tourist area. Because they know the average European or American pays that much for a normal meal in their countries so they don't think twice about it in my country where the cost of these meals is pennies and its usually cooked and stored in bulk and just reheated for each serving.
