This happened a few years ago in my town Facebook group. A homeless man turned up on a bench and people were almost competing to out do each other making him roast dinners & giving him sleeping bags etc posting it on facebook.People who announce their good deeds in a humble brag. Well done you if you bought a rough sleeper a sandwich, here's a special badge I've made you.
In the end the man has to tell them to eff off & then people complained he wasn’t grateful enough and was abusing them. In the end he was moved on.
