The long and short of it all is I'm even more impressed with Deliveroo now having seen how bad their competition is at what is fundamentally the same thing.
It's this sort of stuff that makes people more likely to be loyal to a brand when they're treated right, and the absolutely shit service from Uber means I have absolutely no desire to order from them unless I have quite literally no other choice.
Kudos to Deliveroo for actually providing real and quality customer service.
