make giving to good causes easier by adapting supermarket till so people can add a few pence to their bill to go to charity

helping poor people is a good activity.today i helped a group help poor people in asian.i know my money is not big but i was very happy for helping.you know i never help homeless in my country because they are not poor .they became homeless because they are lazy.homeless in my country is happier than here because they don't endure cold weather.homeless here must endure cold weather,so i pity them.i always give my money to them when i see them on the street...i think it is not a business idea.
