life tip

If someone offers to pick up the tab, instead of arguing with them about it, offer to cover the tip.

Them: "I'll take care of this." You: "Oh, that's very generous of you, thank you. How about I cover the tip?"Taking this approach allows you to avoid the awkward "No, I insist" back-and-forth. It takes a little of the expense off the payer but still allows them to make a generous gesture.
