I can see why the Landlord doesn't want police & ambulance in his pub constantly because this can put his licence at risk when it comes to renewal. But a one-off incident would not cause any problems.
I also see his point about wasting ambulance time. They are there for strokes, heart attacks, asthma attacks, cardiac arrests and other serious conditions, not for anxiety attacks. Since the closure of Stafford A&E at night, the nearest ambulance to a cardiac arrest might be coming from Wolverhampton or Stoke-on-Trent if the only resource in Stafford is being dealing with a panic attack. I really think the public have unrealistic expectations of how many ambulances are on duty across Staffordshire at any one time.
There is some serious lack of first aid knowledge in the general public if they cannot coach and re-assure somebody having an anxiety attack until it stops. This is all the ambulance crew can do...there are no magic drugs to stop it and oxygen will do absolutely nothing for a panic attack.
Fair play to the police for using some common sense, cancelling the ambulance, re-assuring her and sending her off home with a friend to watch over her. All the excitement amoungst her friends probably didn't help resolve the situation.
Unfortunately, had an ambulance arrived, it no doubt would have coded as a Category A 'Breathing Difficulties' call (everything is over triaged just in case it is an asthma attack or similar), so perhaps a community responder, rapid response paramedic and double crewed ambulance dispatched to the scene. No doubt all these blue light vehicles and uniformed people milling around on scene would have made her panic attack even worse, so the crew might have taken her up to A&E in Stoke just to 'cover their ass' (very, very, very rarely, a panic attack can be confused with a small blood clot on the lung, but in these instances they rarely return to a normal state of breathing on scene), she would have spent all night in A&E having her bloods taken, ECG taken, chest x-ray done, and sent home after 12 hours of sharing a cubicle with a drunk when everything comes back normal.
Sorry for the rant, but it is very annoying that people think a 999 ambulance is the right response to every medical incident that occurs out-of-hospital or in a public place, whether that's for a cut finger, panic attack, stomach pains etc. There is always the option of getting the pub or shopping centre's first aider to crack open a box of plasters, take them to A&E or (OOH) GP in your own car (or taxi) or even call NHS Direct or pop to the local pharmacy for some basic advice. All of these options keep the (ever diminishing) number of ambulances free for life threatening emergencies such as heart attacks, strokes, life threatening bleeding, serious car crashes etc, instead of forcing the crew to explain to a dead person's family that the reason the ambulance took 40 minutes to arrive on scene was because they were busy doing the endless amount of paperwork involved with treating a panic attack on scene and leaving them at home. The irony is that the genuinely ill people and there relatives never moan about how long the ambulance takes but those who call for a cut finger are constantly on the phone to 999 wanting to know why the ambulance hasn't arrived within 5 minutes.
