My son had placed a hold mail request, and we get home to find our mail in the mailbox, not the first time either. On my block we have to take each other's mail to one another. Maybe if the carriers get off their cell phones and pay attention to what they're supposed to do, maybe we'd get the correct letters, not be sub delivery persons. There are those that do a great job, but please, take pride in your work that you've chosen to do.


Ever since I was little, we've always had problems with the post office (and apparently, so does half the town). The post office not being open during their posted business hours, closing an hour or two early, locking the door during business hours so no one can come in while they're laughing and joking loud instead of doing their jobs, I've only just sorted out the issue with my mail not making it to my address. I try to avoid the office as much as possible because of their nonsense. I end up driving to different cities when I need post office services, because it's the only one in town. Today, I received a notification that my package arrived at the post office in the morning, but would be delivered tomorrow. Since I'm not going to be home tomorrow, I decided to go pick it up. Here's how that conversation went: PW (Postal worker): *chatting with her friend as I walk in, their conversation ends so I approach the counter* ME: Hi, I wanted to see if a package for (my name) arrived. PW: *stares blankly at me* I don't know Me: ...ok PW: well, how do you know it's here, did you track it? Me: ...yes, I got a notification that said it got here at 10 am PW: amazon? Me: yes PW: it'll be delivered tomorrow Me: ...can't I pick it up right now since I'm here? PW: no because I'm too busy Awkward stare for a few seconds* PW: but it'll be delivered tomorrow After some back and forth, I finally get my package. As she's handing it to me another customer walks in. PW: are you another customer? Guy who just walked in: yeah, but I'm here for to packages PW: ok And off she walks to get his package with no hassle. The post office in mendota is irritating. I've already had to threaten calling the postal inspectors just so I can get my mail, and if any postal worker reads this and decides to start screwing with my mail again, I won't warn about the postal inspectorsthis time. I'll simply make a report to them and have the entire office investigated. This is a small town full of hard working people. Stop being jerks, do your jobs, and give people their mail!
