The McDonald’s Effect

When a store/restaurant decreases in quality as the amount of locations increase.

The new pizza chain down the road isn’t very clean and the employees aren’t well trained. It seems like they have the McDonald’s effect.

The Mcdonalds Effect 

When you didn't get anything to eat because you were not hungry, then upon your friend's food arrival you suddenly become hungry. This is known as the Mcdonalds Effect.

At first Brennan wasn't hungry, then when everyone else got their food the Mcdonalds Effect set in.
