Even if Sprint isn’t your provider (there not mine), you should take the Sprint Wireless Courtesy Test. I scored a respectable 84, but it suggested some minor changes to my behavior. I probably wont change. I do allot of the “wrong things” when I answer calls for work issues. I know I shouldn’t, but if they are important I will answer.
You will be surprised what is considered rude by others. Living in NYC I see rude people all the time. Its not that New Yorkers are any more rude than other people. Their just happens to be so many people around, that one out of 100 on a subway car will be rude. It is just the law of averages! In a small town with everyone spread out, you get a smaller chance of someone being an ass.
