Unpaid Corporate Shilling

I feel so whorish saying it, but I’ve really had some excellent customer service from American Express. Second-most recently was something of an exception, as they apparently didn’t think that I’d be buying a new iPhone 5 minutes after they first became available, but that was easily rectified.
Most recently, they sent me email about some other suspicious charges they had blocked, and those charges were, indeed, fraudulent. So it’s new-card time, and they just sent me email with all the merchants that look to them like folks I need to update my card number with, probably saving me a bunch of statement crawling. Not a huge thing, and not even the most outstanding thing they’ve done for me, but it’s the kind of thing that inspires loyalty.
