When you want to know a people, you go and check out the market places they have. That’s where you find out if people are friendly and how they treat each other. A market place is where money changes hands, where people are haggling and trying to get the best for themselves.
Even if you don’t speak the language, if you see a marketplace where nobody is talking with the sales people, nobody is smiling and everyone is in a hurry to get out of there, you’re either at the end of the business day or the market is not in the better class.
