But now it looks like the home of the Big Mac has another enemy to deal with, and it's causing them a LOT of money!
While they seem to be pointing the finger of blame at the chilly temperatures, the cold hasn't affected everyone as Chipotle saw sales rise by 13.4%!
Another theory is that new menu items have slowed down production, turning the fast food joint into a moderately-quick-food joint!
McDonald's doesn't seem too phased by the stats, as they expect to see better numbers starting in April despite all of the competing breakfast menus on the rise! They just better hope the warmer weather means more people buy Big Macs!
