coaster
there is a modern trend to walk down the street with a cup of coffee on the way to or from work and meetings. of course people also talk on their mobiles whilst walking down the street.
so what do you do if your phone rings and you have a cup of coffee ? well you put the coffee down of course. but where ?
on a street coaster of course. here is one decorated with a cow in the middle of the road.
personally i think it's a little dangerous to walk in to the middle of the road to put your coffee down, but the risk assessment men with their complicated spreadsheets will probably have calculated that for this particular piece of road, the risk of burning your ear with coffee whilst answering your phone is greater
Or you could spill the coffee and scald an innocent passer-by. New legislation must be introduced to stop this menace to society.
