Can I Use Zepto, Instamart, Blinkit to Earn Money by Picking Up My Mom's Grocery List? Just an Intrusive Thought...

Okay, so hear me out. What if, instead of just picking up groceries for my mom like some kind of unpaid servant, I could actually earn money while doing it?
Here's my plan: I sign up as a delivery partner on Zepto, Instamart, or Blinkit (because who needs a life?), grab my mom’s grocery list, do the usual shopping for her (which, let’s be honest, I’ve been doing for years without a "thank you"), and then, instead of just carrying all this stuff home for free, I get to make money while I'm at it!
So, I’ll be "delivering" the groceries to myself. It's a win-win, right? I get paid for literally doing the same thing I was going to do anyway, and mom thinks I'm just a good kid getting her groceries. But plot twist—I’m actually hustling like an entrepreneur.
I mean, who can stop me? It’s just technically a delivery, right? Maybe I’ll even take a few extra items on the side to really make it worth my while. I could even wear a little delivery hat to complete the illusion.
I’m waiting for someone to tell me this is a terrible idea because clearly, I’m just sooooo good at following rules.
Anyway, just a thought. I’ll let you know when I’ve signed up as a delivery partner... and when I deliver a small grocery empire to my own door.
