It looks like American Express is still in the throes of its “risk management” craziness and closing accounts without visible reason. Did Chris, who was just left stranded while on a business trip, shop at the wrong store? Did he fail an internal financial review that nobody told him about? Whatever the reason, it’s a good example of why you should have more than one credit account when traveling, so you don’t have to rely on the whims of any single faceless corporation.
