What do I do?

Hit turbo boost!!

I hope the individual is ok.

From the sounds of the OP if it really is true that an ambulance was not on premises then this is not allowed. It is in the Green guide that any event expecting more than 5000 an ambulance and paramedics should be in situe. Although bizarrely if an ambulance is required then another is called for the emergency, the one in situe is not used.

Also as for the St John's it is the way it goes at most grounds that the on site first aiders respond not the paramedics or doctor. We have doctors for the players and in the first aid room along with defibs. We also try to get anyone first aid within 5 minutes but this can sometimes take longer. and due to the uncertainty I make sure I get the nearest first aider rather than go through the protocol.

As for the stewards at ours they are given first aid training every year although this is basic and the advice given in any situation if you don't feel comfortable get someone else. But if you are then don't go beyond your limits and just make the person as comfortable as possible till help arrives and also reassure them.

I don't know what the headingly set up is as I've only ever been as an away supporter. But you have stewards that also work at Elland road as I used to work there and I knew quite a few when i visited on sunday and I certainly know that they are given first aid training! So I can only guess that the steward that dealt with this situation wasn't very experienced!
