Replacing Cheap Golfing Flags

Golfing flags are rather inexpensive compared to the other costs a golf club has. However it can become of the most overlooked detail as well. I've been to several clubs that have tattered and worn flags that look older than dirt. Why couldn't the club spend the less than $20 a nylon flag and replace them. I know most of us don't even pay attention to the flag because we just want to throw it on the ground to get it out of our putting. Isn't it annoying though when there isn't much to see of the flag when teeing off?
