About 15 years ago got a cab from Ballsbridge home, and he added some extras. When he pulled up at my place he obviously saw the cab, and when I paid him, telling him that he would have got a decent tip if he hadn't overcharged me, he stuttered and said that he was compensating, as he hadn't got his meter reprogrammed yet for the recent fare increase. There had been a fare increase, but he still didn't get the tip.
