Giving to charity can be uplifting for impoverished communities and for the givers themselves, yet many of us seem to be unable to find time to make donating a habit. Luckily, the Polish Red Cross has devised a way to increase charitable donations without much effort. The Very Good Manners campaign uses restaurants’ placemats to inform diners that by laying their knife and fork like a cross on the plate, a donation will be added to their bill.
