Reflections on Kensington Post Office... Improvements?!

The following is from a post on KWT:
Do people agree that these efforts have been pretty much unavailing, or that, at best, the improvements were modest and temporary?

Today, 2 of the 3 windows were not taking debit cards. After I'd been on line for 25 minutes, the one window that was accepting them closed. The manager assured me that another window would open in a few minutes that would accept them. After waiting 25 more minutes on line (my times are completely accurate), the debit card window had not re-opened, and I was told that while the available clerk would weigh and price my packages, he would not let me return to the front of the line to pay for my mailing in cash. Fortunately a man (a stranger) lent me $20 -- if he hadn't, would I have gone 'postal'!
We recently noticed our regular mail carrier was on vacation and received a lot of mail in error. As did our neighbors! We got mail for the building next door and across the street 3 times!

How can the community address this problem? Our local officials seem to have no pull w this federal branch.
