On the 'sign' issue, so many places STILL require me to actually sign for purchases. It's archaic, and stupid, especially with flu season gripping the area. 'I'd rather not!'...
It's such a pointless exercise. I haven't signed my "real" signature on a credit card purchase in probably ten years. I think I've been called out on it once. Now that the signature requirement is gone I wish everyone would get rid of it.
