"Why have thousands of franchisees signed an agreement as onerous as Subway's? Can't they read? In many cases, maybe they can't. "I think a lot of these people are incapable of reading these documents," says Subway executive Alexander Dembski, who designs the two-week training sessions at headquarters for new franchisees. Dembski estimates that 30% to 50% of franchisees are immigrants. Fifteen years ago he proposed proficiency tests in math and English to screen these applicants, but his idea was rejected. DeLuca finally agreed last March, only to discover that 35% of the trainees were failing the new tests.
