Eating in the street and LITTERING!

I have no particular objection to people eating in the street - and we are talking baked spuds and pasties and sandwiches here but so many people just chuck their half empty containers on the floor as they go back to the office or leave them where they sat for someone else to pick up. No disrespect to these two young women I happened to have photographed on the Market Square who put their rubbish in a bin. I went past a metal bench in the city the other day and there were four baked spud trays just resting on the bench accompanied by a pile of cold baked beans on the ground. Urgh. Litter, what do you think?
