I disagree, if they can show that the food delivered is at a substandard level to what they serve at the restaurant, I believe that they would have a very good argument that their brand was being damaged.
any food product gets cooled off when delivered
unless they can show there’s some deliberate damage (very very unlikely).... it would appear they have no case
they lose all rights to the product when they sell it
it is not theirs anymore, they have no further say
now, if the private delivery were to appropriate their trade mark logos, then that would be actionable
just my 2 cents worth, for free too!
so its worth at least as much as you paid for it
ha
happy day to you,
ps: a major portion of taxicab revenues are delivering grub like this (and booze) to residences....same idea...nothing new now that i have heard anyways
