Talk about kicking someone when they're down.
Apple has received yet more criticism of its iOS 6 Maps app - this time from Transport For London.
TFL employees often leave hand-written messages outside Tube stations to inform users of transport issues - or cheer them up with a piece of advice or a joke.
Yesterday one Twitter user noticed that staff at Hackney Wick station were killing both birds with one stone, by issuing advice for users of Apple's Maps app.
"For the benefit of passengers using Apple iOS 6," the notice said. "Local area maps are available from the booking office".
The app has been widely criticised for featuring out of date information and low-quality business listings.

Here are our ten favourite errors found so far in Apple's Maps app:
Apple Brings Back Woolworths
Apple was just as distraught as you when Woolworths shut down. So they brought it back. Our Price, Electronics Boutique and other defunct stores are also listed.
Apple removed public transport search from its new Map app - but included Aldwych Station which has been closed since 1994. And was never in Lincoln's Inn. Also, the Sir John Soane museum is not located in the Fields, but around the edge of the square.
Stratford Upon Avon? Never heard of it.
Apple's new maps seem to not know that Shakespeare's birth place exists.
Apple has decided to stay out of the whole Falklands/Las Malvinas debate by removing all directions, roads and towns from the islands.
The Beauty Of Cambridge
Apple has turned the ancient spires and colleges of Cambridge into a wasteland with its recent Maps app. And has moved Downing College from the outskirts of the town into the centre - miles from its actual location.
Bad Luck, F Chamberlain And Sons
This greengrocers is listed on Apple's maps - but has been closed for 15 years.
This man's 35-acre city farm is named Airfield. It is not an Air Field - but Apple has decided otherwise.
Apple Loses Its Own Store
The Apple store in Sydney is listed as being on the other side of the road than it really is. Oops.
St Katherine's Dock Loses Its Water
The marina of St. Katherine's Dock is now filled with cement, according to Apple.
Hagley? You Mean Dudley.
The town of Hagley is listed as being the town of Dudley - at least seven miles away.
The town of Uckfield is almost entirely missing from Apple's Maps.
