thanks Wakeke...I'm encouraged to bite my lip now. I've been here 20 years and had no more than two of those scenarios in that time. But I didn't have your capabilities! My window came down first, and my words were first and last.... and I felt like I won. But that didn't make me happy. I will try your method, I think its better.
That one man you encountered does not represent the myriad of Qatari's who are helpful, hospitable and thoughtful towards others.
One expat woman I know had difficulty with her car one evening, and standing by the side of the road, she was passed by dozens of 'expat' drivers. Then a Qatari came by, and stopped, sorted everything out, made her feel safe, and got her home to her husband and kids. She was grateful yet shocked that it was a local person, and not one of her 'own kind'- someone alien to both her nationality and culture - who had been the ONLY ONE to come to her rescue.
I couldn't start my car downtown Doha, and it was (guess who!!) a Qatari who came and sorted everything out for me. No one else wanted to know. So I'm sure you'll find that this one stinky incident will be heavily outweighed by many more good deeds done by his compatriots.
