In my opinion it should be even more than €3 for most deliveries, I think this is subsidized by VC money and unfair conditions to the delivery people.
Disabled and elderly people not being able to procure their own food isn't really a new problem and also isn't a problem that most first world societies have ignored.
So I'm not really sure what disabled people using a service have to do with the (allegedly) unfair wages of the delivery drivers.
It was a direct response to the idea that the only people ordering from food delivery services are lazy, which is simply not true. I was incapacitated last year due to an injury and wasn't able to leave the house for a couple of weeks. I would have really struggled without Wolt.
If you're incapacitated for a longer time, you might still want to check out if any meals on wheels services are available to you. I actually know a few colleagues (in their 30s) that started getting those since working 100% from home. It can be quite a bit cheaper. And if you're like me it would also be healthier, because every time I order food it turns out to be something like burgers with fries ;-)
If people will go get their own food, try to guess how much the delivery guy earn then when the whole business goes down?
From user of the service point-of-view, the salary of a middleman delivery guy is irrelevant. It's only about what service is being given and how much does it cost. If the cost is too high then people will simply not buy the service. Food delivery is not a necessity after all.
3€ for delivery isn't really unreasonable, it's actually quite cheap. Let's say that it takes 10 minutes all together with going to restaurant pick-up/waiting, then going to drop off. With full utilization that would be 18€ an hour. Now remove 24% of VAT: 13.68€. Rest of the taxes and so on... In the end 3€ is probably too low. Even with some 30% from whole order price.
