I am a firm believer on old school man against machine. Turned 55 & I have not changed my way of play. It gets people complaining in league & tournament play. When I get screwed by the machine I respond. I always state that I will replace the glass for anyone if it breaks, & double down on glass if I destroy one. If it is not me I will not clean up the tempered glass remains. But warranty the playfield glass. Interested to see if other events do not banging on the glass gets the wrath of events or owners.
