'Grammar vigilante' corrects rogue apostrophes on business signs in the dead of night
If you eye roll dramatically every time a business adds a redundant apostrophe to their sign or fails to add one where one should be then you'll want to high five Bristol's self-proclaimed 'grammar vigilante'.
The anonymous figure, who is a qualified professional by day, trawls the streets at night to fix grammar mistakes on the signs of local businesses.
Using his 'apostrophiser' which he built himself, he either places a sticker over redundant apostrophes or adds missing apostrophes.
He kicked off his nighttime hobby over a decade ago by removing the second apostrophe from 'Amy's Nail's' and since then he has tackled the signs of a variety of businesses from estate agents to hairdressers.
"What I'm doing is sticking on a bit of sticky-backed plastic," he told the BBC.
"It is a worse crime to have all these errant apostrophes on shops and garages and I just think it is going to teach the youth of tomorrow the wrong grammar."
A documentary on the 'grammar vigilante' will broadcast on BBC Radio 4 tonight.
