That's been a staple of restaurants for decades. The restaurant would charge the delivery fee on the bill, but you were still expected to tip the driver directly. People who didn't became well known to drivers. It was a good idea to just tip the driver...
Oh yeah, we for sure remember our regular stiffers. Wonder why your pizza is always cold and your drink has been steadily shaken since I left the store? Maybe if you threw me one dollar in tips you'd see some improvements on this, but the last 20 times I came out here you didn't break me off shit.
Maybe you should focus your anger towards your boss who isn't paying you enough and not on the customer who is unfairly being expected to subsidize your salary.
Boss paid me better than any other drivers in my area, he was the owner operator of a small local spot who refused to raise his prices, to the degree where at one point we were taking a loss on wings during that chicken shortage. He was still putting his three kids through college and I was the only employee who wasn't the owner, his wife, or his daughter, had he hired another I would have had to lose days and therefore money. Sure he could have paid me a little more, but I'm not mad at him, he paid me fair for what I did and I was unfirable. We're actually still friends and I was sad when I had to move on, as was he. He's a good man, a hardworking immigrant who deserves everything he has, he had nothing when he came here and worked his ass off.
You're not just talking shit about my previous employer, you're talking shit about the only one I've ever had I call a friend. You can eat that shit you're talking, buddy.
