I think that Poles take great care of their cities and towns
Yes, not bad with it here, the cleaning services are quite efficient, so you will never see such views of rubbish flooding the streets like in southern Italy.
What bothers me is throwing litter out of your car while driving in the countryside. I feel like puking when I see all those crisps wrappings, fast food boxes and empty bottles lying in the grass next to rural roads. Yes, after some time they are dealt with by the services, too, but if some Poles adopted a better approach, there wouldn`t be the need to waste money on cleaning the roadsides.
