Why don't I pay more attention?

I have never before been riding so much taxi in Hong Kong since Ella was born. We were just not comfortable taking her on the public transport. Of course, having our own car would be great, but at the same time it's not that convenient to drive and park in this city.

As I was sitting in a taxi I was wondering if I ever been driven by the same taxi driver twice? With many thousands of taxis in Hong Kong I don't think it is very likely. Although I cannot say I have ever really paid attention to what the driver looks like, except that it is a man. So far I have never had a female taxi driver, but I know they exist.

Even if I have been in the same taxi twice I wouldn't have noticed. On the other hand, does the taxi driver recognize his clients?
