If at a football ground (bear in mind the same arena may be used to very large concerts), If you hear “Constable ERIS” being requested to report to gate X or wherever, well that is where the problem or potential problem, eg fire, bomb threat etc is.
Constable ERIS never seems to obtain promotion, but the “ERIS” bit stands for “Emergency Reponse in Stadia”, oro so I was told.
ONce, in a desperate attempt to get tiny bit of money, I tried stewarding at a large football ground in Glasgow, and this is what we were told.
(It is rather a shame you lovely people do not know me personally, becaue you would get a grt laugh at the idea ofo Celyn stewarding in massive arena full of crowds, whether the detestable football, or even only large concerts)!
Incidentally, I admit to having been quite taken with the fact that they used the word “stadia”.
