I'm not going to give 2 tips to the delivery guy
Why would you even consider giving two tips to a delivery guy?
Because I want him to know that I am appreciative of the time he takes to deliver things.
Giving two tips would have been unusually generous. It would be fine to tip him just once, though. You can make it as much as you want.
I left a 1 cent tip.
When you tip a delivery driver, you should ensure that the tip is fair and appropriate for the service that was provided.
