Personally, I am fed up to the back teeth with these people: security guards, bus drivers, underground staff, PCSOs and - indeed - some police officers. Before going on the good old "interpersonal skills" course, and the "diversity awareness" course, I would send them on a "using common sense" course. If someone is asleep, smells of alcohol, has beer cans etc nearby, the probability is they are SLEEPING and have been DRINKING. Even if these informants are reluctant to "shake and shout" the patient, they could at least shout from a safe distance. They even tell us that they "didn't want to get involved" - Sorry?? - you're a SECURITY guard; it's your JOB to get involved. Frankly, I believe the problem is largely the lack of English as a first language. More often than not, security guards at shopping centres etc have only the vaguest grasp of English, and this is now the case with many bus drivers. Calls to people "collapsed" on buses frequently have little or no information, because the bus controller tells us that the driver "does not speak English". Even these much-vaunted PCSOs seem to use little in the way of common sense. I had recently to explain to one at a supermarket in east London, that a female on the floor intermittently shaking and going rigid, was NOT in cardiac arrest but was fitting, and his attempts at CPR were at best a waste of time. Strangely, when the patient stopped fitting, and started to come around, he seemed to think he had saved her life. Rant Over.
