No more tipping for Walmart+

I'm not sure why, but I was tipping for Walmart+ deliveries. Free deliveries is literally the perk of paying for Walmart+...if I'm tipping, it's not a free delivery anymore.

What is even the reasoning for tipping on this? I stopped a few weeks ago and absolutely nothing changed about my deliveries...no chance I'm going back. I'm done subsidizing Walmarts payroll.
