This brings to the surface the age old argument of whether you should have any alcohol or drugs in your system as a passenger on an aircraft. The state of some people on board these holiday flights, in an emergency they are going to be a massive hinderance to those of us who are sober and want to get off.
It isn't going to happen because loss of alcohol sales equals loss of profit.
To expand that meaningless cliché 'Safety is our primary concern......unless it costs money'.
