What point are you trying to make considering you live in the largest multicultural part of the country and there are more foreign names there than English ones now and not many English people will need or want jobs delivering food from fast food outlets. It's a sector that's obviously going to attract migrants and people with less opportunities for good jobs.
Also, regardless of names, how do know some of these delivery drivers aren't total freaks and weirdos that take pleasure interfering with peoples food if they're having a bad day? Your food could've been spat on, masturbated on, urinated on, or injected with something, for all you know.
It happens in Supermarkets and shops under CCTV so try and imagine what someone twisted could do to your food in the back of their own car with nobody watching.
I would never allow any of these online delivery companies and random unknown drivers to handle my food EVER. If I can't go and collect it myself....that means I won't be eating that food.
