Beyond that. It's just mental that we treat tipped jobs like that in the first place. No other jobs are expected to be paid at starvation wages and only be able to make in with me through the kindness of strangers. Generally the people in that situation are homeless or unemployed. Not working full time.
A tip for a gratuity is supposed to be for treatment above and beyond the standard. If you're a restaurant relying on people to pay 10% extra than the cost of a meal or more to their server in order to actually pay for them. You just need to charge that much more for the cost of a meal and pay the employee. I would gladly pay 10% more if I knew that it meant the employee would have security. And that I would not worry or question whether or not the tip I left was enough.
