One of the problems for shopkeepers is they need to apply for planning permission from the council to site a waste bin on the pavement outside the shop. If they ask the council to provide one there is a long process of meetings where more important matters are dealt with first. This can result in their request being shunted further and further down the agenda until they get a warning regarding the amount of litter outside their shop. Its a no-win situation sometimes. And even if they do get permission it is then up to Joe Public to use it, not the shop keepers.
