The experiment in the corporate restaurants showed a significant
increase, prompting Quick to roll out the menu item to 14
additional restaurants (now a total of 22 nationally).7 In these
restaurants, only halal hamburgers were sold; these stores became
popularly referred to as “halal Quick’s.” Quick contended that offering
both halal and non-halal options necessitated two different
production lines which created potential for mishandling and
cross-contamination, thereby threatening consumer confidence
(Quick, 2010).
