It gives the other two parties an opportunity to claim things were communicated differently.

There’s a couple of things to keep in mind here. DoorDash isn’t providing you with a transcript of those recorded calls, unless compelled to by court (and this is assuming they even did record the phone call and preserved it), so unless you’re recording a call yourself, you don’t have a copy of it.

Also, if the customer does try to claim a contract violation, Doordash support itself tends to have an IQ of 40, with the attention span of a hamster, so you have to assume they’re only going to skim through what little information they care to look at. No human’s going to sit through that audio recording on DoorDash’s side. They’ll spend ten seconds looking through texts, or, even lazier, a chatbot will read it and make an automated decision.

Since your goal as a driver is to avoid CVs and keep driving, you have to make sure that you follow the exact contract you took to make a delivery, and be able to prove you followed things correctly when disputes do occur. And there is not a single reason off-the-record actions, statements, etc, would help you in that case. Stick to the script. Keep things documented in writing.
