I was taught that the bowler on the right has the right of way, so in the first frame I always start first, if I'm on the even numbered lane, or wait the the even numbered lane to start, IF THEY ARE READY.
As to waiting for the anchor, that is, in my humble opinion, a bunch of hogwash and slows the game down, a lot. You bowl when it's your turn. The exception is if things are out of sync because Doug is in the bar and you are in danger of having a bowler up on both lanes at once - then you wait to get back in sync. But if everyone bowls when it's their turn you will rarely be far out of sync, and you'll get done 15 or 20 minutes earlier.
