Regarding this, sports bars in particular pay a pretty hefty fee to have public-view television service, especially regarding access to all pro-league games. I'm sure they'd be paying more in general if they opted to mute or turn off the screen during ads (since the network expects x% of the restaurant's viewers to see and hear the ad, so they get the advertiser to pay more for access to those viewers, subsidizing the restaurant's actual monthly bill).
