If you leave a good tip then giving it in cash will help because they do not have to declare it on the taxes. Even though they will have to pay taxes on a percentage of their total tickets they can sort of pocket the rest.
He leaned out of the booth and looked around to make sure the coast was clear, gave her the high sign, and then she lumbered over and grabbed the tip.
My wife and I once watched a Spanish speaking family leave their table and they took tips from two tables as they passed them. I now always give our waiter/waitress their tips directly as I always over-tip and do not want low-life thieves stealing the hard-earned money from the wait staff.
I’m surprised that Spanish speakers would do that, because a lot of Spanish speakers work in restaurants and know how hard people have to work for their tips. But congratulations to you for tipping well!
I always think big tipping is a cheap ticket to heaven, because you’re not giving it to a bum on the street who will either drink it or put it into his veins, but you’re rewarding somebody who is working hard, taking a lot of abuse, but still doing a good job. So blessings on you!
