That wasn't what I said.
"Pint of Thatcher's please"
"£2.49 love"
Hands over £2.50.
"Don't worry about the penny, just stick it in the charity box, nice one." Etc.
Why bother with the collection boxes then? Pretty sure everyone involved in collecting for Weston Park Hospital (local cancer hospital) is a volunteer and that's generally the box I chuck my coppers into.
It is pointless but I chuck every 1p / 2p that I get in change at a pub / shop in the charity box and I guess a lot of people do. Sure that adds up to quite a lot.
