I was in a taxi this morning and towards the end of the journey, the driver made a comment "where do all these people come from?" I was distracted in the back, sorting something on my phone, and I thought he was talking about the heavy traffic. I made a comment in reply something like "yes, and where are they all going?" and he replied "thieving, I expect". I was confused, looked up and noticed two black people had just crossed the road in front of us. He must have been talking about them. I was pretty shocked and the journey came to an end so I didn't say anything, but now I'm wondering if I should, because surely he can't be saying racist stuff like that to customers? My only hesitation is that I get taxis all the time and I'm likely to come across this driver again.
wwyd?
