Can honestly say I've rarely had a bad time at any post office except for the very occasional grumpy clerk. A few are long-wait shitshows due partiolly to short staffing, but more so to people who have no clue...they'll walk in holding, say, a jacket and say, "I need to mail this," then have 8 million questions about the different ways it can be shipped, then ask to borrow tape so they can put a box together. Like it never occurred to package it at home before coming in. One woman wasted almost a half-hour wanting to know why she couldn't address a package in Russian. The USPS site is incredibly easy to navigate and answers 98% of any questions someone may have, but apparently many never visit it.
