Last week London's Camden Road branch of Sainsbury's apologised after advertising for a "creative and ambitious artist" to refurbish its staff canteen for free.
In the advert, Sainsbury's offered a volunteer the opportunity "build your career and develop your reputation".
"Leave your mark by doing what you love and do best," it added.
Obviously people were not happy that Sainsbury's – one of Britain's leading retailers – was asking artists to work for no pay.
But things took a different turn when artist Graeme Snow-Matter wrote an excellent response to Sainsbury's in the form of an advert looking for "a well-stocked supermarket to voluntarily restock our kitchens".
A brilliant response by an artist to a corporation asking artists to work for free:
"No qualifications or experience is required as we are simply intrigued and excited about the free stuff you can offer us," the Snow-Matter wrote.
Here is the epic response in full:
Artists are looking for a well-stocked supermarket to voluntarily restock our kitchens. Gain particular experience in the good industry whilst satisfying our need to feed ourselves and live comfortably. We seek to find a diverse supermarket, so we encourage suppliers of food from all ethnic cuisines to apply.
Why not put your skills into action? Artists are giving you the one opportunity to build your customer base and develop your reputation through the creative community.
We are looking for the market to bring their own style to transform our kitchen shelves into an environment that allows positivity and inner peace through the scopes of being able to feed ourselves.
By crafting food into a reality for artists, you are recreating what is originally a basic human right to survive on our sought-after skillsets. The new delivery should give artists an atmosphere to look forward to and emphasise on the idea that they don't have to work on an empty stomach.
No qualifications or experience is required as we are simply intrigued and excited about the free stuff you can offer us.
As freelancers, artists are proud to represent a diverse skillset with which you can benefit from. Happy artists offer great works and continued success.
Get your brand recognised. Share your goods with the heart of creativity. Leave your mark by doing what you love and do best.
People loved the response and, despite not knowing its creator, thanked the artist for highlighting how ridiculous it is to expect an artist to work for free.
In a statement to BuzzFeed News on Friday, a Sainsbury's spokesperson said the firm is having discussions with the Camden store.
"The advert was placed in the local paper following a colleague discussion around ways to improve the canteen and offer an opportunity to the local community," the spokesperson said.
"It is not our policy to hire volunteers and we are sorry for this error of judgement," they added.
