But did you know that since 2014, the prices of popular dishes on the McDonald's menu have doubled?

This is the highest rate among all fast-food chains analyzed by FinanceBuzz.

It has far exceeded national inflation, which has caused the cost of goods to rise by 31% since 2014.

The result? As a result, fewer customers are visiting McDonald's, and global same-store sales fell by 3.4% last quarter.

This is well below the 4.7% expected by Wall Street.

Last year, the New York Post reported that in Connecticut, a Big Mac combo costs $18, which sparked a backlash.
