I leave at HT normally.
This 1 game, versus Wimbledon back in the day, me and my mate actually did leave at HT, we had a lil sesh before the game, so were utterly bombed, the game was prolly the worst game ever, just before HT I said to my mate the game was sending me white, he agreed, so we just koffed at HT and went back to my mates.
It ended 0-0.
