Tipping is a strategy used by the employer to get the employees mad at the customers instead of mad at the employer under-paying them. Tipping is extra; therefore, it should NOT be expected. If these waiters/waitresses want more money they should find a different career path. Or instead, change the ruling and make the employer pay them more money per hour and rid the system of tips. The employer does this to gain more money and make the employees dependent on extra tips in which are now seen as the norm because folks are ignorant.
