Going Postal?

I know that it is quite cliched about someone going postal. But jesus! Has anyone been in a post office line recently. I really do believe that one, if not all 3(rarely do you find 3 or more actually ready to assist customers), could take out someone at the drop of a dime. More noticeably, each other. They seem to be the most unhappy people you encounter as a consumer. Granted, individuals may surpass the USPS's finest in terms of sheer anger or discontent. But overall, I think they have cornered the market on vocational unrest. Just remember the next time you see that person in line with about 5 boxes and wants to send each one a different method, some with signature guarentees, some without. The look in the staff's eyes should say it all, "if tomorrow wasnt Saturday, you would be dead!"
