I got the better part of £1000 out of Southern trains some years back when I landed painfully on my coccyx on un-gritted stairs. Evidently, weather forecasts were for other people and despite the obvious problem none of the station staff were qualified to put grit on the platforms and steps.
Reminds me of the other week, passing through West Croydon station, someone had spilled a drink and there was a little warning board next to it. Six hours later? It was still there, unmopped. Literally a ten-second task.
