Different Paradigm
Over here the National Petroleum Agency (Pemex) had to setup a system to check each pilots breath and BP before going on duty to fly in the GOM, this was due to soo many pilots flying after a long night out with the ladies.
On my first job having only about 90 total helicopter hours, I remember flying copilot in a Bell 212 with a pilot who all the sudden said "you have the controls, fly anyway you want just don't shake me much" and after a couple of pax drop offs in the pads, he disembarked and emptied his stomach, he was still drunk, and was happy because I got to fly for following 5 hours!
I also recently worked for a US company in an WHO contract where one of the pilots flew drunk from time to time and the base manager didn't really care, neither did I for that matter.
