Craigslist manners, and people who don't have them.
If you aren't coming to pick up your shit from me for any reason, I don't care what it is, just give me a fucking call and tell me that you're not going to come so I don't have to wait by my phone. 1 minute call.
"Hey, Peter BUTT, I'm not gonna be able to swing by. You should probably let it go to someone else. Thanks."
Really, that hard for the common courtesy? Assholes.
