Free Cleaning for the American flag

Unless you have spent some time living in America, you might be surprised by the esteem many Americans feel for their flag. Down our way, many houses have the stars and stripes mounted on a flagpole from the front of their house. Schools have it at their entrance. I had not thought about it before, but these flags always look sparkling clean, and this is why. I was picking up some dry cleaning today and while I was waiting, I read a bold notice pledging as part of the cleaner's pride in their service that they always clean the American flag for free.
