It doesn't take much to make another person's day - but it isn't something we often think about doing. One man has shared how accidentally giving his pizza delivery driver a 140 per cent tip left him with a warm fuzzy glow in his heart.
He explained how he ordered a pizza after having a bit too much to drink - not realising he paid for it online when placing the order. So when his pizza arrived, he dug into his pocket and gave the driver $30 (£24) to cover the food alongside a 20 per cent tip on top of that.
Taking to Reddit, he said: "[The driver] said 'Thank you!' very enthusiastically which made me realise in about two seconds that I just gave him double the money for the order, which he would obviously receive as a tip."
