I know of many operators filling up their waste bins before pick up, year after year. My main source had a huge sink hole in their warehouse, & would push games in. Same with their leaking roof destroying games. Years ago very few people bought old games. The operators would sell some, but hated or refused to service them. I have also sent over 100 early Bally electronic pins to the dump, after removing some parts. If I can get em's working fine, but usually if its more than a couple of hours to fix. The owners don't want to pay.
