Somewhere along the line, somebody will have to deal with fewer irate passengers who just missed their trains because the signs were too small and verbose. I would agree that it is unlikely for anybody who can do something about the problem to connect the unfortunate signage with the irate passengers, though.
How do you think the employees in charge of the signs will benefit if they start omitting the phrase?
