Interesting responses. A couple of years ago I was on a bus between two locations in West Yorkshire when a disembarking passenger informed the driver that somebody on the upper deck had passed out - having seen the individual boarding, almost certainly due to consumption of alcohol and/or illicit substances. The bus company's response ...
Epilepsy and related illnesses can also be dealt with in an uncaring fashion, but complying with "the Rules" of the establishment.
My brother suffered severe epilepsy throughout his life, and his attacks whilst inconvenient, were not generally life threatening. We, the immediate family, knew what to do. But when one occurred during a family visit to a garden centre, the staff followed procedure, and called an ambulance - we were not consulted. We eventually caught up with him waiting in A&E, and after a long wait he was seen by a junior doctor. This was the first time that the doctor had seen such a case, and he didn't know what to do, but at least I got his agreement to discharge my now shivering brother, so that we could take him home and put dry clothes on him - he'd "fallen in the water" at the garden centre. A few hours later, my brother now in dry clothes, and warm again, was as good as normal - i.e. not very good at all, but that's serious epilepsy in practice. Time lost due to staff at garden centre following their rules - around three to four hours.
Unfortunately, despite my experience as an H&S professional in industry, I can't offer anything better than "rules"... Perhaps if I'd been wearing a stethoscope at the garden centre, I might have been allowed to get my brother home into dry clothes several hours earlier.
