This idea is not original to me, but I like it, so I am posting it here...
When you pay at a restaurant, if you are using a credit card, leave 1 dollar as a tip. Then give your server an appropriate tip in cash. In this way, there is a trackable record of a 1 dollar tip for tax purposes, and none for the cash. If the server or restaurant is audited, their buttons are covered.
I would love it if this idea spread around. Imagine all trackable tips all being just 1 buck.
It will work until its a liberal worker who will then post the receipt to some social media complaining of only receiving a buck but won’t say a word about the cash.
