I’ve noticed a couple times I had hour long sessions and even with the pre/post talk still finished 5 or 10 mins early. Never really bothered me, but I could see how it could annoy someone. I do hate the clock checking in a session, so I guess I’d rather it be shorted than having the Domme check her watch constantly. I did used to session with someone who used to set a timer on her phone before we started which worked well. I also had the opposite happen once where I checked my watch upon leaving to realize we had gone an extra 30 minutes. So I guess it works both ways some times.
