to stop smoking or to pick up their trash they have been very polite to comply and thanked me. Most people want to do the right thing, but get away with too much. SPEAK UP PEOPLE! I am a 5 foot 2 woman, but I am not scared to tell Qataris or whoever to stop doing something. In 8 years no one has ever responded in a negative way when I have called them on their behavior (except stupid parents with babies in the front seat). Be brave. It takes us all to make a change.
