I live in Mexico City and over the years US influence has been greater and greater here, so there are not a lot of differences with life in the US as far as goods, services and daily life, but one of the things that is different is how honest people are in the US, an example:
We were on our honeymoon and my wife left her wallet with US$1000.00 on top of a pay phone at the Miami airport. We relized this about 30 mins later when we were at the car rental counter, we went back to get the wallet but it wasn't there anymore. Just as we were leaving the airport we heard my wifes name on the PA system, a cleaning lady had found the wallet and returned it intact. We gave her a nice reward and went on our way.
I was amazed by that, that doesn't happen in Mexico, people are generaly good here but if you lose a cell phone you will never get it back. We travel to the US a lot and being that my wife is the Michael Jordan of losing things, we have had that type of good experience another 3 or 4 times. I love that about the US.
