My wife usually gets the praise after our gigs and quite right to. We also let performers know we have been moved by their music. Applause is a strange beast, a quiet intense piece often receives similar applause, whilst a brisk up tempo tune gets whoops and hoolas!! It's only at the end of evening that people directly express their true depth of interest. Leadfingers is someone who has always been post performance positive but his observations are sound that we sometimes are too polite. But that's who we are.
