It's an established fact that people are afraid to sit on public toilet seats.
If you manage a business with toilet facilities, you are responsible for the health and well-being of your customers. Sharing a toilet seat is like sharing your toothbrush or bath towel with strangers. It's a risk people prefer not to take.
Until now, there wasn't much you could do. Your maintenance department or janitorial personnel can't be expected to clean toilets after every use. Paper toilet seat covers, hand towels and toilet tissue used to line the seats provide little protection, clog the plumbing and increase the cost of supplies.
Being aware that a problem exists and doing something about it are two different things. You can no longer ignore the problem.
