Respect the Islamic beliefs of Qataris and Bedouins: Although there is no legal obligation to wear the hijab, women should not wear tube tops or tight-fitting clothes, although there is no strict rule and women are free to dress as they wish. It is perfectly acceptable for any nationality to wear the traditional Qatari dress, the thobe.
When you have dinner with a Qatari, do not expose the soles of your feet to him. Also, do not eat with your left hand, because the left hand is considered the “dirty hand”. Also, do not try to shake hands or hand over a package with your left hand.
If your Qatari friend insists on buying you something – a meal or a gift – don’t! Qataris are extremely hospitable and there are usually no strings attached. As a rule, it is customary to plead for the change.
