What’s your preferred way to wind them up? Jumping in one at the airport and asking them to go to the Cork Airport International Hotel? They love this after they’ve waited hours for the flight. Or how about eating chips and curry in the back of the cab on the way home and whispering to your partner “do you have any spare napkins?” And “do you think it’ll come out?” Or repeatedly asking “are you busy tonight?” “How long have you been on for?” My favourite of late was in a white Mercedes E-Class a couple of months ago, asking the driver “this is a fine car, is it an Octavia? It’s nearly as big as a Superb.” Alternatively just complain about all the taxis parked in cycle lanes. They love that.
