So we set off towards Habana whilst the driver had an animated discussion with his boss with his mobile pressed to his ear with one hand and the other deftly steering around the many potholes in the road. Well we got all of half a mile before the rear tyre blew with a loud bang and we ground to a halt. We all jump out in double quick time, and though not up to F1 standard it must have taken no more than three minutes to remove the cases and the spare tyre from the boot (this time it was encouraging to note that it did have some tread and air inside it), jack up the car, change the wheel, restow the wheel and the cases, and be back on our way. I got the impression our driver had done this before. Further mobile conversations en route ensured that we were transferred to another more roadworthy Vauxhall in a layby a few miles down the road.
Such is life in Cuba - we were told by our guide Adrian on the first day, as he explained why our vehicle would not be arriving till the following morning, that Cuba is not like western countries and things don't often go smoothly and without a hitch but things always get sorted in the end and with good humour. Our new driver got us safely to the airport on time - he told us that he was a lawyer but had been driving taxis for a few years because the salary as lawyer (less than 20 USD per month plus staple rations) wasn't sufficient to keep him and his family. As a driver he had the chance of making quite a lot extra in tips.
So, go to Cuba, enjoy Cuba, and tip generously.
