Transition Lenses

I have never really understood transition lenses. I mean, I get the concept but why would you ever buy them?
1) You look like a complete idiot
2) They never transition fast enough
3) What happens on a cloudy day?
4) If your office light is too bright do they turn to sunglasses even though you’re inside?
5) You look like a real dumbass

I only know this because a man walked in to the caffe and they were still trying to transition. He couldn’t see the Menu board and then only one lens transitioned. After I had to tell him all the options on the Menu AND made his drink for him did his transitions finally transition. Dumb.
