There is an account on Twitter called You Had One Job which showcases amusing examples of incompetence. Specsavers vans that have crashed into lamp posts, supermarkets which have somehow placed a sign saying ‘baby products' above the booze aisle, road markings which say ‘turn left' but have an arrow pointing right...That sort of thing.
I sometimes check to see if the Department for Work and Pensions (DWP) has made it on to this site yet.
