Is it wrong that I'm thinking of tipping the pizza delivery person more than my wife thought I should?
What makes you want to tip the pizza guy more money?
He was really polite and did a great service, I want to show my love for great service
It's a kind and generous gesture to give a larger tip than would be expected. You will be encouraging the delivery driver to continue providing good service by doing so.
You can't understand if you haven't had personal experience.
Providing a good tip for the service you receive is generous and kind. Doing this is a wonderful thing.
