Sir - I am often in Cornmarket, Oxford, on a Friday evening. There are three establishments in competition: McDonald's, KFC, and Burger King. They all have adequate seating upstairs. However, McDonald's alone closes its upstairs seating at about 7pm, so that customers then have to take the food and the eventual litter elsewhere, whether they really want to or not.

But I wonder if there is some by-law which could compel this restaurant to use the seating which it has throughout the evening, rather than disgorging people on to the highway? It is an anti-social way to operate, right in the centre of our city.
