"Many offices have beer on tap, wine in the fridge, and hard liquor on the shelves as a perk for employees."
Wut ? Who does that ? It's one thing to have a few pints with the colleagues after work at a suitable venue, but actually in the office seems a bit much.
Soooo many rent-a-desk places have free beer these days, which means many many start-ups, particularly in and around London, have free beer, at least in the afternoon.
