OK we're at the 4th and I *think* I've been good. Now, I did write a letter in to the restaurant we ate in DC where the server did a poor job. But I wrote it to let them know we had problems that they should probably fix if they want to have happy customers. I don't see that as a complaint. I see it as constructive feedback so they can improve. As "teachers" in this world, we often need to give constructive feedback so people can get better.
