Well, for a long time the population as a whole in the US managed to kill pay first gas stations. Pretty much everyone just kept driving when they saw the "pay first" signs and the pumps refused to just pump gas. The inconvenience of guessing how much gas you need give the attendant a $10 or $20, pump gas, go back and collect your change was a far worse experience than pump the gas, pay whatever you owe. Wouldn't surprise me if the ad based gas stations just lost a 10-20% drop in customers if there was an alternative nearby without the ads.
