^^^ The professional game is obviously played very differently then from the way that the amateurs played in my local pub when I lived on the edge of Sheffield. I often arrived at the pub, on a freezing cold night, and/or in pouring rain, to find my entry barred by a guy with his back to the door. If I tried to ease it open, he'd turn round and mouth '"Game on!" to me through the glass, making it clear that he'd be committing a hanging offence if he allowed me to open the door.
It wasn't much better if I was already in the pub when a darts match started. Conversation, even at the very quietest of levels, was strictly prohibited in the bar when a darts match was being played; it was all taken extremely seriously!
What was annoying though, was that most of the guys actually playing darts were utter rubbish at it! I often had to wait outside, in the pouring rain, for ages while the two players finally got down to both needing double one - and then having to wait a good deal longer until one of them actually managed to score it!
