"If you're a customer,boo. Real fans don't boo their own. It's called support through thick and thin. #toomanycustomers"
"Stunning week in week out what I see amongst away/home supports. Ask an away traveller If they boo. 99.9% NEVER"
I know I'm going to get shot down for this but surely if you pay for your ticket you have the right to voice your feelings. And I think the away traveller point is flawed. Even if you don't agree with people booing surely it's unfair to criticise them as they are just expressing their feelings in a different way ?
Booing and singling out your own players is horrendous, and in the past City fans have behaved terribly towards some of their own players. However there are times when a Boo can be productive, ie after a bad 45 etc, as long as its not aimed at one player, and then the next 45 you are then cheering them on.
