As much as I am the usually the first in line to slam the WTBTS I do remember a bloke becoming very ill at one of the conventions; the ambulance was there within minutes and he was rushed to hospital; I dont think they would openly prevent anyone calling the emergency services in such a situation.
However should you be a child and go the elders complaining that Bro such and such was behaving inappropriately when babysitting, then strangely enough there would be an absence of emergency services then!
