Downingtown's Finest Residents at the US Post Office

Me being me, I kept The Man at the PA Dept of Revenue waiting for my tax return. I mailed it tonight using the Automated Postal Center. Long story short - a stream of about 10 to 12 people came in while I was mailing my stuff. Each one asked, "Is this a post office where you can mail taxes?" I replied, "Sure. If you use the APC, it will definitely be postmarked 4/15/2010."

What responses did I receive from the people? Here's a list: "Oh, do you work here?", "Fuck me!", "Fuck that!", "Fuck them!", "Fuck this!", and last but not least, "FUCK!"

Seriously residents of Downingtown, is it that hard to figure out how to mail something? I mean, I assume you've mastered the touchscreen at Wawa.
