Disclaimer: I worked at a Pizza Hut (takeout/delivery only one) around 1990. I delievered, which wsas a fairly good gig, as you kept your tips. There was no delivery charge at the time, and I purposely worked at one in the 'burbs, far enough from my house (in Detroit), that I wouldn’t (a) get shot at (b) carjacked, or © stiffed for tips. Or at least, all of those things would happen less often.
Anyhow, I can understand not tipping when there’s a delivery charge–that really SHOULD go to the driver. At least when I worked, you could submit expenses for gas somehow but I don’t think I ever did–I believe it was too much effort.
I do understand why SOMETIMES they won’t let you make any substitutions or remove anything–if they pre-prepare the pizzas, especially for the common popular ones. We didn’t do this, but I bet many places do.
Best parts about the job, besides tips, were being able to listen to the radio in the car a lot while working, always hoping whoever answered the door would be a hot, horny 18 year old girl short on funds (never happened), and getting to take unclaimed pizzas home with me (well, they didn’t go home–I’d just go to school and give it to friends… it was a commuter campus but I knew a lot of student teachers with offices who would hang out and drink late into the night, and if I showed up with pizza around 11:30… well, you can bet that went over well!)
Now, I actually never patronize the big chains. Besides being permanently sick of Pizza Hut, I live in Cali, and while basically noone here knows how to make a decent pizza, the local jernts are definitely the closest. We actually order something weird now, half-modified-Margherita, half-meaty-thing, which I am fortunate for automation for… because I just call and give my phone number and ask for the same thing I ordered last time… they pull it up on the computer, and off we go. Me and wiff happy.
