4. More Equals Less

At Domino’s, more equals less when it comes to pizza toppings. In other words, when you order five or more toppings, you’ll actually end up getting less of each topping. But, it’s not because they’re trying to gyp you or anything like that — although that could be part of it, too.
The fact of the matter is the more toppings you add to a pizza the messier it gets. So, in this sense, Domino’s is looking out for you, the customer. And, here’s another reason to avoid more than four toppings: it can get pretty expensive.
3. Domino’s Used to Go by a Different Name

Before Domino’s was called Domino’s, it went by another name. In 1960, brothers Tom and James Monaghan purchased Domi-Nick’s, an old pizza restaurant in Ypsilanti, Michigan. The restaurant’s name was changed to Domino’s Pizza, Inc., in 1965. Delivery driver Jim Kennedy came up with the new name.
Unfortunately, the new name landed the pizza chain in a bit of hot water. In 1975, Amstar Corp., maker of Domino Sugar, instituted a trademark infringement lawsuit against Domino’s Pizza. Five years later, a federal court ruled that Domino’s Pizza did not infringe on the Domino Sugar trademark.
