I agree with Sandy also.
I have no issue hearing people from other places speaking in their home language when they are in the presence of their families, but it really irks me to go into a store or business and have no idea what the person is saying. And for Gods sake DO NOT give me attitude when I ask you to repeat yourself a bit slower so I can catch what you just said. This happens a lot when you call AOL or it seems a lot of telemarketers need a brush up on their English. We have a store down the road owned by a family from the Middle East. They are the sweetest people, but I often avoid their store because I don't understand them.
It seem there are a lot of businesses (nail salons) that are owned by Asians. (I have no issue with this, actually I think it's great). It really bothers me when they are in a group talking in their language and laughing knowing full well I have no idea what they are saying. They could be saying something really hurtful or making jokes about me. I wonder how they would feel if that were to happen to them?
If I were going to a foreign country I would at least have the decency to try to learn some of the language or at least know the most important ones. (water, food, hotel, bathroom, and bar LOL)
