Working as a group of 3

I was doing a Shop & Deliver at my local grocery store the other night. It's the grocery store closest to my house so I'm there a lot. I noticed this group of 3 people who seemed to be working together. I've seen it here and there, but it's usually a boyfriend and girlfriend, or maybe a friend tagging along, or a parent doing it with their kid. I didn't think much of it. I just went to grab personal groceries and i see this trio again, and I'm thinking to myself, there's no way they're doing this together as a trio. The money is shit if you're doing this on your own. Sure enough, I hear a ping come in, and I hear one of them say, "bitch take it, We'ze need the money". I lost my mind. That's so inefficient, other than you can knock out the grocery orders a little faster with the extra hands
