That was the stewards' view lancsdave. People asked why they couldn't stand in the area behind the seats. To get surprised by the steward responding that it was a seated area. We did get put in that stand because of the rain. To get saturated and drenched at the front of the stand anyway.
In the end they did let Burton fans stand up, but in the uncovered corner. When our fans attempted to stand there in the 2nd half, they got moved by steward who told them they weren't allowed to stand there

.
But like Smudgie said, 50 fans or so standing behind the seats isn't exactly going to cause great amounts of danger to fellow supporters.
I did read about your fans having problems from your own stewards when you played Bradford, over flags. So the pushiness from the stewards didn't really surprise me.
My dad told me he had spoke to an Accrington steward at half time. And he got told that they were hoping to put a roof on the away end next season. And there were also plans to change that bus shelter like side stand we were in into a bigger stand.
