I did not care if people knew anything about bowling when they came in to open bowl. They were in there bowling spending money on soda, candy, beer, etc. They showed up to put money into the business that paid me. If they asked me questions about the game I would answer to the best of my ability.
As far as the color of lights not all centers are that way so you can't say that the first ball is amber and second is red. I have seen some places that both are amber or both are red. There are also some that have one light for first ball and two lights for second ball. Every place is different on that.
