Waffle House serves around 272 million eggs per year, according to its website, well surpassing even its titular waffles, of which it sells just 124 million. "We are continuously monitoring egg prices and will adjust or remove the surcharge as market conditions allow," the statement ended.

Restaurants are being forced to up their prices as ongoing outbreaks of highly pathogenic avian influenza (HPAI) -- or bird flu -- continues to limit supplies.

A national egg shortage and skyrocketing prices have led to Waffle House adding a surcharge on eggs to keep up with the lack of supply.
