It's Martin Luther King Day today and there is no mail. A bummer but it's a holiday. What's perturbing, though, is that the U.S. Postal Service has announced cuts in postal routes and changes in others. These moves are being made to pare expenses in the current recession, which has resulted in a marked decrease in mailings, hence revenues, generated by the finance industry. Here in the Lehigh Valley, five routes have already been eliminated and 84 others altered. More changes are on the way, including new faces among carriers. New people mean a lack of familiarity with the routes and the customers on them. For customers that means a lack of trust, which is the real bummer.
