I've seen that gri gri screw a number of times over the years. I am very paranoid and triple check them every time. Great devices, but people seem to do this a lot.
Every single time I attach a grigri, or someone else attaches a grigri whose belaying me, I will pull on the climbing side to make sure it locks.
That's pretty much maximizing the disrespect for your belayer.
Does double checking that your partner has their harness double backed also count as maximizing disrespect?
What about asking if you are on belay? What about calling down "got me?". What about the dozens of other checks and double checks that are done all the time to climber and belayer when climbing?
Would you forgo a 1 second check to maximize your own safety?
