My husband and I have met quite a lot of nice Qataris. We found them to be welcoming, gentle and generous folk with a good sense of humour. One drawback was we met them separately. My husband with the men in the Majlis, myself in the inner quarters. If we were to meet them outside it would be my husband and I with only the husband. I wouldn't say its a matter of how highly educated, its more a matter of how conservative.
Still, I don't see the harm in asking. They understand we are not completely familiar with their culture and if its not suitable for them they will simply tell you so politely.
