Last week, Starbucks started applying free food and beverage rewards directly to customer Reward Cards instead of sending the plainly-marked, black-and-gold, freebie postcards through the US Postal Service. I know that I'm far from the only person who complained repeatedly about the disappearing postcards, but Starbucks corporate probably won't ever admit that they found a serious problem with rampant postal worker theft.
Early in the program, I was receiving a couple of postcards ever month. Over the past year, I was lucky to receive one card every two months, despite the fact that my habits hadn't changed and my online account showed that the postcards were being mailed regularly.
I'm not suggesting that postal workers are less trustworthy than anyone else. I imagine that as, a group, they're about as trustworthy as everyone else, which is to say that given the opportunity to steal with virtually no chance of getting caught, many of them will steal.
