And you're doomed if you don't notice that you have to add it to the order. There's no going back!
I ordered table delivery, then went to use the dispenser thingys but they were empty, so when the guy brought the food over, I asked if we could have some sauce please. He said they're 10p each now sorry, I said no problem but I only have card. He said you have to add it to the food order, you can't just order sauce.
Sauce-less fries are very sad.
(Obviously light hearted, I know we have lots of bigger problems right now, but this is right up there with 60p carrier bags!)
