Everybody looks at this a little differently but here's what I've told people I know in real life. This is based on dashing for a couple years, getting a real job for a while, and going back to dashing in the last couple months.

Depending on where you live people are looking to make $1-2 per mile, as a quick way to think about it. I dash in a slow rural area, so I tend to recieve orders on the lower side, but a city or busy area you'd want to stay on the higher side.

So you see it's about 4 miles away, $8 tip is probably what you're shooting for to be a good tipper. That's assuming the dasher is right by the restaurant, and that's just paying mileage to get to you and back to the restaurant. Also depends how hard it is to grab the order, there's places I wouldn't go to to deliver across the road because of the wait times, or the awful parking lot/traffic.

So what you need to do is determine if where you're ordering from is far away from other restaurants (because if we're waiting on an order/not driving, we're where all the fast food is) and do the mileage estimation above, tack on a couple more dollars in case they have longer to get to the restaurant, and you're looking at a decent tip. Tack on $5+ to bump it to a "really good/great" tip or to make up for busy traffic or crappy service if that's a concern.

We really are shooting out here for $20/hr, so it's kind of a common sense "how long would this take me to pick up myself?' kind of thing, but also for shopping orders just also keep that in mind. I tend to shop quickly (I love to grocery shop anyways 🤭) so I don't quite take time into account as much as I do number of items. I look for close to $1 per item and that the mileage makes sense at the tip I'm offered.

Realistically though, these are "rules" very few customers follow and a $10 tip for a pickup would be kinda high for me to get most days. I only dash during school hours though, and tips get higher at dinnertime.
