There are a couple of difficulties with that idea. One is that when you remove the auto gratuities, it goes as a black mark against your housekeeping staff and your dining room server. You probably don’t mean to hurt them, but it does. Another difficulty is finding the people you would like to tip and then how much will you give them. The person who clears your table at ocean view café, as an example. You might have a different person every day. How do they get tipped?
and finally, there is one last difficulty. As it is, all tips go into a tip pool. If you remove the auto gratuities, and you give your waiter and assistant, waiter and housekeeping staff, cash tips, they have to turn them into the pool. The only way they can keep cash tips is if you leave the auto tips in place and give them money over and above the auto tips. So in fact you’re not helping the situation at all and you’re not actually able to tip the people you want to tip.
