I really appreciate having a post office nearby where the workers are so helpful and congenial. No matter how many people need assistance, they take the time to respond to any inquiries I have and always provide service with a smile. Thank you!!


Clerk 08 interrupted 3 times; never answered my question & assumed she knew what i was asking. She ruined the appearance of my professional mail pieces by slapping on so many stickers (tracking, postage and 2-3 Priority Mail) on the front of the 9 X13 envelope. I use white envelopes and custom address labels so they can be seen and read and present my company with a professional look. I do not use white envelopes with custom labels; so they compete with a sea of crooked stickers applied by a "sticker-slapping-happy" clerk!. When I pointed this out, she even bragged about using so many! This person is clueless about postal piece appearance!
