I don't think anyone is genuinely thinking or saying that in a smug tone (except tbf maybe this specific incident because it appears they're also a bigot and possibly a scammer). Anyone spending hundreds on DoorDash because they actually want to, and not as some sort of weird scammer power play, is probably either not thinking through their financial decisions entirely or has some other reason to do so that isn't malicious or even purposely dismissive of the people that donated to them.
