Maybe the best strategy is to tip low when placing the order, then increase the tip after delivery to reward the guy who needed the money enough to take your order with a low tip.
Seems more fair to me to require the company pay their employees a fair wage and benefits rather than redefine those that work for them as contractors to dodge those obligations.

People steal Amazon packages regularly, I think they would not hesitate to steal something that says "Instacart" on it.
/s but only kind of.
Besides, I don't want to have to keep a supply of small bills around just to pay a tip that I could have just put on my credit card. I rarely pay in cash these days (even pre-covid)
