Just that really
Not thought much about it before but tv program on at the mo showing how they keep oxford street clean and amazed at the amount of effort they have to put in removing gum
They say each piece of gum costs about 3p but £1.50 to remove from pavement 😳 plus thousands of litres of water used in the clean up
I think it's banned in Singapore.
Or just somehow to make it unacceptable to drop it on pavement?
