Good to forewarn the people involved but will probably fall on deaf ears.
Some fans can be as thick as mince and some Stewards can be too, so you would think there would be some common ground to reach an understanding.
The problem with stewards is not just at away grounds, I can recall a few years ago waiting my turn to leave ICT's car park when a car drove round the back of lines of cars to be stopped by a Steward and I overheard him saying out loud to the driver 'So you thought you could sneak round the back you F##king C##t' (think I could see kids in the back of their car too),I thought a bit over zealous for someone wanting to leave the car park, I am assuming that the said person didnt keep their job very long.
So unless you can prove that the stewards are being overzealous and unreasonable its better to do as they ask.
