I have never heard of a pizza chain doing this. If I went in to pick up a pizza and asked for parm and peppers and they told me I'd have to pay, I'd demand a refund and never order from there again. That's like McDonalds charging for ketchup, or Popeye's charging for hot sauce.
Demand, really? I can tell you that acting big is NOT the way to get good service at a pizza place. A couple of weeks ago, a woman came in upset because she wanted a small pizza, and the driver that took her order didn't know about the special that she was asking for, and sold her a large one instead, thinking that he was saving her money. She had found the special she wanted after placing the order, and decided to come in and make
sure we understood how outraged she was.
Now, if she had given me (the manager on duty) time to speak, I would have apologized for the inconvenience, and given her the order at the price of the small special, as well as thrown in a side of something, or if she couldn't wait for that, a drink of her choice. Instead, she demands a refund, and I oblige her, taking her pizza back in the process. She then curses at me in front of another customer, saying that it's "fucking bullshit" that she won't have lunch before work now. I asked her to leave the store.
I can tell you that no one behind the counter at a fast food place cares where you get your food. That being said, a little courtesy will go a LONG way in these situations, as pretty much anyone that I work with will go above and beyond for a customer that feels wronged and is courteous about it, but will do the absolute bare minimum for anyone that starts treating them like shit.
