Thankfully I've not experienced this often. The one that sticks in my mind was in a recording studio years ago. Needless to say, I was gob-smacked when he told us his reasons. Shameless. I won't name the guy here, but I won't be working with him again.I've done a lot of FOH, and worked with a lot of FOH folks, and never met anyone who did that. Then again, the folks I've worked with you wouldn't call "lazy". Apparently we live in different worlds.
