On the other side I got a call from my local post office to help with an English speaking customer. He was an army officer, which he told me many times, and he was waiting for a package that was supposedly sent 1 day service from Ventura California. First off there is no such thing as 1 day service to Mexico through the US Post Office. As he was ranting he told me over and over and was very upset about the fact that the people at the Mexican Postal Service did not speak English and he did not speak any Spanish at all. I don't know why he would come to a Spanish speaking country and expect his language to be accomodated.
When I got here I had to learn Spanish because not enough people speak English. That is just the way it is, but this guy was very upset that nobody at the post office spoke English.
