They have made the mistake of taking an "all or nothing" approach. I can understand them stopping people from actively trying to preach to shoppers, which is what caused this policy, but forbidding all prayer is over the top. On the other hand, if they allowed some prayer, but not all prayer, they would probably get sued by someone.
Oh well, that's America today.
someone can quietly sit there, close their eyes, and pray however they want. its the thought that counts, not the degree of public display.
