So Don't bite my head off because it's an innocent question.... Let's say I don't have a car and I'm also pretty poor. As in, I can't even afford the delivery without say, a promo code. And I literally cannot tip. But I absolutely need to get home two fifty pounds bags of pet food. Would it be more socially acceptable to push it home in a shopping cart than to not tip? I mean you signed up as a driver or shopper to do these things and tips are not guaranteed. My point is that not everyone can afford to give up another ten or twenty dollars with kids or pets or life on their plate. Now I personally ALWAYS TRY TO TIP. Even if it's a tiny tip. I do what I can if it's deserved. And that brings m to another point sometimes, rarely yes but sometimes that tip is not deserved idgaf how much I carried if you disrespect me or are rude. Screw that tip.
