I routinely use services like grocery delivery and grocery pickup with the usual big players. The people who bring my groceries to my condo front door, or car trunk are helpful and polite and helping me with a chore that I hate. To thank them, I offer them cash tips. I don’t make it awkward; all I say is “Thank you!” and offer the tip. And they refuse! Please, just take it. No one is looking. You deserve it. It’s free money. I know you explain that you’re not allowed to. But you drove to my place in your own car and you’re sweating from lugging the stuff. Just take it. Everyone needs more money to live on.
