For fast food companies, offering diners discounts on meals may no longer suffice. For example, Taco Bell was able to attract value-seeking diners without instituting widespread discounts, the report said. As covered here last week, the fast food giant pulled back on popular digital deals to fund its new “10 items for under $3” menu. The Reuters report added that other chains saw that promotions had little effect on the pressure facing lower-income diners. Burger King, meanwhile, reported strong sales growth, which management credited to promotions as well as efforts to improve operations and food quality.
