I was stood there that night and these werent kids, they were early to mid twenties and have been to the odd match and were just on the wind up,albeit out of order and your right the stewards should have sorted it, however he was abused and ignored it moving away, in his defence he quite clearly wasnt up to the task, and the two chief stewards were nowhere to be seen.
When we play away at some bigger clubs eg Northampton, or Rushden their stewards were no nonsense behave or elsa types ours are just normal freindly guys/girls who are just not used to confrontation, and thats not a dig at them just how it is.
