But no one is sitting in them. Could be the following: "A sign above each seat shows a cartoon of a roly-poly passenger saying "Priority chair for obese people." said Metro.
"It may be that they don't want to think of themselves as fat or they resent being put in with pensioners and the disabled," said one manager. Well it doesn't take a rocket scientist to work that out.
Any sign saying "large people welcome" or "fat people sit here" isn't the most subtle approach.
Why not just have the seats and let people gravitate to the ones they're more comfortable sitting in? With cut backs on the Tube, perhaps we'll see seats of half the normal size saying "Priority seating for size zero's".
