During an earnings call on Feb. 10, McDonald's CEO Chris Kempczinski said that the number of low-income consumers visiting the fast-food chain's U.S. restaurants was "still down double digits" during the fourth quarter. The startling change in consumer behavior comes after McDonald's faced backlash from consumers last year for hiking its menu prices. In October, the restaurant chain also suffered an unsettling E. coli outbreak at multiple locations, which forced it to temporarily remove its Quarter Pounder from menus. Since then, McDonald's has rolled out deals such as its $5 Meal Deal and its brand-new "Buy One, Add One for $1" deal to try to boost sales. McDonald's makes a bold announcement In its latest attempt to win back customers, McDonald's is now promising not to add a surcharge on eggs, unlike its competitors. This comes amid an alarming bird flu crisis in the U.S. that is causing egg shortages and price hikes nationwide.
