The founder of a British homeless charity was left feeling "quite disheartened", and did not find it amusing when discovering fake £20 notes in a donation box."We've got two fake £20 notes in our donation boxes. It was collected from a pharmacy, locally, and obviously someone thought it was funny to put in fake £20 notes," said Arif Voraji in a video post on Facebook."I felt quite disheartened," the Leicester Mercury quoted Voraji as saying. The fake £20 notes stood out amongst the usual petty cash donations, Leicester Mercury reports, saying the 38-year-old was touched by the generosity shown towards the less fortunate, before realising it carried no monetary value. "At first when I saw the £20 notes I was surprised. Normally we only get small change like 10 pence pieces. I thought someone had been extremely generous and kind," he told Leicester Mercury.He soon realised they were of pink colour around the edges and made of thin paper, BBC reports. According to the Bank of England, counterfeit notes carry no worth and holding onto or passing on counterfeit notes is regarded a criminal offence. According to the BBC, Voraji said the money could have been used to buy a sleeping bag for a homeless person, or gloves. The Leicester-based organisation feed homeless people on a weekly basis, collect unwanted clothing items and provide assistance to struggling families or those who moving into temporary homes, according to their Facebook page.Since Voraji posted the video on November 23, the charity received a total of £160 through real £20 notes donations, writes BCC.
