Not only have I done this to send a little "message", but when I was a rookie it helped me resolve an issue with a really clown of a customer. Every day this guy at a particular dock would act like a dick towards me. He would talk all sorts of crap, and say out loud "You'll wait until I'm ready to sign got it?" It would piss me off like crazy, but it was a pretty big stop, and I wanted it off of my package car. Anyway, on Thursday's though this guy would run over and almost give me a handy. I couldn't get his lips off of my ass fast enough on Thursday's, and being so new I had no idea why. So one day I bring this up to the regular driver that I would cover for, and he laughs and says "Well Thursday's are pay day. He wants that payroll you're delivering. If I was you, and this guy was treating me this way, I'd hold that payroll until 4:59 PM every Thursday until he changed his tune". I thought about it and decided to try it. One Thursday came, and although I was buried with a lot of packages for this guys stop, I moved it around ALL day until just before 5 PM. I pull up to the dock and this guy's going nuts. He's screaming at me left and right. Apparently they have an armored van that pulls into the yard on Thursday to cash checks for people. Like a Mobile Check Cashing Van. A lot of people, including this clown, were pissed that they not only didn't get their checks, but couldn't cash them early. So he's screaming at me, asking me where the friend I was early, and I calmly say "Well you treat me like S every day but Thursday's, and I have to wait for you to sign when you feel like it every day but Thursdays, so from now on I'll come at 4:59 PM until you start taking care of me the second you see me." He was pissed, and cursed me out some more, and then called in a concern. My center manager pulls me into the office the next morning and asks me what happened. I explained to him how this guy acts towards me daily with the insults, and purposely making me wait, and told him I had had enough. My center manager actually sided with me, oddly, and without saying it, smiled that he supported my decision. I'm not sure what he said to the customer when he called him back, but the next time I went there, and EVERY day after, he kissed my ass like it was made out of Budweiser and chocolate. You don't treat me like S and get away with it. Customers sometimes have to learn a hard lesson about how to treat their delivery people. We're there to make your day great if you're courteous, but act like an ass towards us and you'll still get your stuff, but at the end of the day. Hey, you might just be closed some days too by the time we get there. Oh shucks. Sorry. I'll try harder tomorrow! haha. Nope. If you're gonna S all over us you'll do it when we decide it's time, not at your convenience!
