Glad I'm not the only one who feels this way about Doordash. I never use it. Don't even have an account.
As already mentioned, getting anything fixed is a nightmare, there are tons of errors, and then of course you have the issue where stuff arrives cold.
I got out and pick up my own stuff. Even pizza (which I agree is the only realistic thing to have delivered without much fail).
I am, in general, a self serve guy. I don't even use bellmen or valets. I will carry my own bags and park my own car.
