Issue with DD sending drivers 8+ minutes before when we set order to be ready

I swear the second we get an order, doordash is immediately finding a dasher to send our way to pick it up. I can put it as the order will be ready in 20 minutes, and they’ll still send one to be here in 5. We cook everything to order, nothing is premade, it will not be ready in the few minutes it takes for the dasher to get here. It makes us have to set the wait time for DoorDash to be longer, like lying that it won’t be ready until 30 mins instead of saying ready in 20 so they’ll wait at least 10 minutes before sending a dasher.

It makes the dashers mad at us when it’s not ready for another 10+ minutes if we keep it as the real ready time, and it makes us stressed trying to rush it out. But lying to say it’ll take longer just makes customers reluctant to then order seeing the wait time is so long when it’s not, it’s just us trying to make sure the dashers don’t get here 5 minutes after it’s placed.

We live in a big city with tons of dashers to the point there’s like a months long waitlist (I used to dash), there’s no real reason to send one so early when I know there’s a ton that will be available closer to when the ready time approaches.
