I think there is a federal law that requires each post office to have one crabby employee on staff. They do have an image to maintain, you know. He might just be the one you have to worry about going postal on ya one day if you don't play by his rules. Fortunately most of the postal employees I run into are very friendly and do their job very well. We have one at my post office that I try to avoid.. I think she has something against me because of the high number of heavy Priority Flat rate envelopes I used to mail. But all the others are great folks. There is a rule about not using the "free" postal supplies for anything other than their intended use.. but what I want to know is.. How did he know you were using the Priority labels as your address labels if you had already cut off the Priority part and the form #?
