How do you feel when an artist doesn't interact with their audience during a concert?

I've always liked seeing bands or artists banter with the audience in between songs during their performances. I feel it shows a connection with their fans and that they're having fun as well. But when they go out there and don't do so much as a greeting or a "thank you" when given applause, it just seems like they're out there to just get their show over with; there to clock in and clock out without seeming to actually enjoy it. One could argue that at the end of the day, that's all they're there to do anyway, sure. But you can't tell me it doesn't make for a greater stage presence when they're interacting with their audience and getting the crowd hyped up during their concerts.
