Courtesy. Please Find Some.

So we all know common sense isn't all that common.
Courtesy is another one of those things that aren't common.

One example is using the phone to let people know if you are going to be substantially late.
If you're going to be late, or if something happens that makes you late, let the people who are waiting KNOW. Cell phones are useful for that reason. It takes less than a minute to call someone to let them know that you are late, instead of just having them wait around stupidly.

It is fine that your car broke down or if something else happens, but PLEASE let people know that you're going to be late. It's not that hard.
