As a Gabbai Sheni I have noticed that often the Gabbai has a difficult time getting someone to daven from the Amud. Some Shuls have paid Chazonim, yet others can not afford that. What can a Gabbai do in order to get people to be willing to Daven from the Amud?
I was talking to a friend of mine today about this question and he told me that recently he was in a Shul and no one wanted to Daven Musaf for the Amud. The Gabai has already Davened Shacharis and read the Kriyas HaTorah. So the Gabai made a loud announcement "Good Shabbos - Thanks for all of you joining with our Minyan. I am leaving now and will come back once someone goes to Daven Musaf" and he went out of the Shul. Within a minute someone went up to Daven.
