Maybe I don't understand the issue correctly, but several services exist in .cz that you call, tell them „I need X from shop Y“ (any shop, incl. food) and they will go there, buy it and deliver it. I don't think this should be forbidden (yes, I get potential quality complains mistakenly directed to the restaurant, but you already have the same problem with any external delivery service or reseller...). Example of such service (they even have an English website): https://idodo.cz/en/products/dodo-courier/ https://idodo.cz/en/products/dodo-courier/ (of course the impersonating issue is different)
