I do use it, myself, but to see who called me, but I never put a person on hold to answer the call unless it is doctor or someone like that calling me regarding on appointment of health. And then I tell the caller, I will call them back.
Anyway, I usually hang up after waiting several minutes while the "more important call" is answered.. And every old person I know has this. And if you wait, you might talk to them in a few minutes or several if you hold on long enough. I understand emergencies, doctor's offices calling back, etc. But personal calls?
Also, if I hang on long enough I get disconnected anyway. So that is pet peeve that probably only old grumpy people like me have. But I have it and I practice what I said I will do, even if it is one of my good friends.
