Because if they don't, the customer will go to the competition who does.

Customers who are elderly, obviously don't have others watching over them, and are mentally and/or physically degraded? You expect those customers to exercise the choice of the market?

Ah, the "Perfect Competition" fallacy!

Going to court is unpleasant, since it will mean you are going to spend the rest of your life fighting. You may count on the fact that some portion of people will be fighters, and willing to sue, but thats statistic is of little comfort if you are the one fighting.
