Actually, I have a question that ties in with this topic, as I'm still relatively new to the pinball scene and am still learning what's considered acceptable behaviour and facepalm-worthy. For instance, in our local league, once the "doors open" on league night it's normal to just walk right in, yet my first couple league nights I ended up knocking first... I'm not used to just walking right into someone's house! : P
Anywhoo, my question: If someone was selling a pin I wanted and I went out to buy it, then noticed other pins all plugged in and everything, if I agree to buy the machine being sold and pay the guy, is it OK to ask to stick around for a little to play some of his other pins before taking off with the purchased pin, or would just the act of asking that be a faux pas?
