Been there too! My place isn't even that hard to find, but it pisses me off when my kids are looking forward to some Edo and it never comes. The refund is fine, but we're still hungry and now it's 8 pm, now what am I supposed to do?

In my experience they don't refund if the driver is 20 minutes late because they went the wrong way or because they decided to take multiple orders. I've even had them drop my food off at the wrong place when I was standing right outside my door waiting for them. The people at the other place tried to tell the driver it didn't belong to them but he just left it with them and left, my neighbour gave it to me. When I complained Door Dash said that because I got my order there was nothing they could do.

But that blows for the consumer

I can't remember the last time I paid anything in cash that wasn't my kids allowance. But on top of that Skip the Dishes ( I assume door dash too, but I used to drive for Skip so I can say them for sure) shows the driver how much they'll make on the delivery and if they don't like it they won't accept it. If I'm paying in cash then all they're being shown is the base distance rate and they'll all deny it.
