Everyone always likes to blame things on our "litigious society," but I wonder if we don't invite the problem by doing things like posting that sign. We are obsessed in this country with not offending others, with empty bureaucratic gestures. It's almost as is we want to put lawsuits in people's minds. Think about all the useless words on an airplane, especially during the safety information. Is there anyone who's never worn a seatbelt, and if so, is there anyone who couldn't figure it out or ask someone around him?Drives me crazy.
