Travelling through an unfamiliar country on business is a tiring and bewildering affair.
One of the first, and arguably most frustrating, situations happens immediately after you land. Stumbling out of the arrivals hall, with little idea what time of day or night it is, not least where on earth your hotel is, it is tempting to collapse into the nearest cab.
And I did exactly that a few days ago, stepping out into Cairo where I was greeted with a scrum of taxi drivers. The most persistent ended up charging me about £20 for what turned out to be a relatively short journey. I was, however, grateful and was duly whisked away to my hotel. It was only when I met a colleague in Egypt did I realise that Uber was flourishing and I should use it instead. No cash, no haggling on price, and a reliably efficient route. Exactly the same journey in reverse? The equivalent of £2.
So I left Egypt with a bruised ego and a renewed love for Uber.
The system works. Excellent.
