Nudge: Ordering the Big Burger

Ever wonder how Five Guys burger nudges you to get the big burger? The Nudge blog has the answer:

Anywhere else, said larger burger would be deemed a “double” (“double cheeseburger”, “double double”). Not at Five Guys; for them a “hamburger” is two patties and a “little hamburger” is one patty. And, on the menu board, the hamburger is on the far left column and the “little hamburger” is in the next column over. The difference? 220 calories and about $1.50.
