One of the local clubs decided to put in some type of cushioned hard court to lessen the strain on the old folks knees. The result was more cushioning, but huge dead spots scattered randomly in the courts. This would result in a ball you expect to bounce 5 feet in the air only going 2 feet. Playing was not fun due to the wild variations in bounces.
Of course there are tons of bad high school courts around. Paint over concrete, super slick surfaces, lots of cracks which are never fixed, no dividers and the courts really close to each other, ect.
