Yesterday while out in the mother in laws car which we're using while ours is being repaired the missus started complaining about vibration in the steering wheel. As it's been lying in her garage most of the time over the last few years I said it could be the tyres just needing blown up. We headed for the nearest petrol station to find an air pump. We used to use the ACCA garage and blow them up ourselves but it's closed down so went to the YPF petrol station instead. Found no public use air pump existed so had to use the on site Gomera round the back.
We found the cheery chap sitting playing with his phone obviously with nothing to do so he promptly checked the tyre pressures and filled them up. My wife asked him how much and he replied just give me what you want.
I won't tell you now how much she gave him but her idea of a tip wasn't the same as mine. I'd be interested to know how much you would have given him for all of three minutes 'work'?
