Nitpicks. Prices are good (specially outside of large cities) but I believe that "Coffee is $0.15" is a typo. A coffee will hardly ever cost you less than 0,5€. And $0,7 is for a 200ml beer not a pint.

> most businesses prefer to deal with the foreigners.

Businesses prefer to deal with costumers able to pay more (or quicklier) for the same services/products.
