McDonald's was notorious for that. The Cheeseburger/Double Cheeseburger was often cheaper or included in deals&promos, while the Hamburger/Double Hamburger wasn't. I was challenged once as to "why don't you just buy the hamburger if you want to hold the cheese", I asked them to ring it with the hamburger and it came to a higher total, so I asked to ring it as I originally asked instead.
