Just another reason why I prefer Diners over AMEX. As soon as Diners expands more in the US to include more retailers, I willbe extrememly happy. For the mean time, I am using Diners with a Marriott Visa. I am thinking of getting rid of my Gold Rewards Plus American Express and going Starwood Amex.
Overall, Amex does not seem to be concerned with customer perception. Maybe this is a cost saving technique since their stock has been depreciated??
