It used to be more common. Back in the 90s when I was working in an office we'd often head to the pub for Friday lunchtime and roll in later in the afternoon. Going along for a free lunch and a few beers with visiting sales reps was also pretty common.
I couldn't do it now - the thought of nursing a proto hangover before I've even got home seems insane in retrospect. God knows how much productivity used to be wasted due to work time tipples.
When Boris (?) cut the Foreign office contribution to the world service I thought it was a terrible idea but good old Auntie kept it ticking. This cut compounds on those bad decisions when soft power is one of the few things we have in this world.
