I know my dart playing habits are a little odd... I usually hit my local bar alone, on an off night, grab a pint and head straight back to the dartboard in the back corner where I'm least likely to be disturbed.
Throwing darts tends to be something of a meditative thing for me. I zone out and aim for the bullseye exclusively and I've gotten pretty good at it over the years.
Unfortunately on occasion this draws unwanted attention. Drunk attention.
When approached I usually tell people that I'm "just practicing" which puts most people off, and they leave me be.
The thing is that I really enjoy playing a game of cricket on occasion, but most people really aren't serious players. Even worse, the average bar patron is usually a little too confident in their ability... They talk a good game, but then they throw like they're pitching baseballs.
What's a good/polite way to separate real players from enthusiastic drunks when approached at the dartboard?
