"Perhaps it's this Michael Pender"

Maybe, but I somehow doubt it. The OP talks about getting "Pissed with people", which is an Americanism. The British would say "Pissed off with people". "Pissed" without the "off" to a Brit means "drunk", of course.

Mike Pender is a Scouser, and would almost certainly have said "Pissed off".

IMHO.
