London Local Authorities Bill [Lords]

I am slightly puzzled about the corporate causes of litter. Is my hon. Friend insinuating that if somebody walks into a McDonald's, buys a Big Mac, fries and a Coke, leaves McDonald's and drops litter on the floor, the responsibility for the litter lies with McDonald's? Surely the only person with whom the responsibility lies is the person who dropped the litter, and the company cannot be held accountable for what its customers do.
