I like the UAE idea....name and shame and kick 'em out.
I have never had an issue with a Qatari but I have had with
'diaspora groups'
I whacked someone on the Corniche who was about to grab me.
The Qataris I know are very distressed if they know if someone has upset me in their country.

Dont forget some people pretend to be Qatari when the aren't. this happened to a friend in a car accident. She got a Qatari on the phone PDQ - low and behold 3 mins later the 'rude Qatari' was a 'pleading Egyptian'
