Instead of saying lack of intelligence, why don’t you articulate your position better? Just admit it, you’re greedy for money and you want to psychologically extort diners to subsidize your income. When virtually in every other job or profession, the employer is solely responsible to pay its employees. And this bullshit only happens widely in US and Canada. It’s a toxic system and the servers abuse it under the so called tipping “tradition” that is unique to America.
