Saudi taxi driver 'learns' a lesson

We have just returned from a vacation abroad and I have to share with you a saudi story about our travels. On our first attempt to leave the country we realized at customs that we were missing our saudi visas and we had to retrieve them quickly. We normally would have called a driver but couldn't afford to wait for one to arrive so we decided to take a taxi from the airport to our destination 10 minutes away. A saudi taxi driver approached us first out of a whole mob of drivers and led us to his car where he started putting our bags in the trunk. Before opening the car door I insisted on coming to a price, though he kept trying to get us into the taxi. He finally quietly quoted an exorbitant 80 riyals, to which I offered a more reasonable (and still overpriced) 50 riyals because we were in a rush. Unbelievably, he said no to this with about 30 other drivers watching the whole thing and ready for business. So we removed the bags and just went to the next car, much to his dismay. Upon returning to the same airport about 2 weeks later on our way home, the same taxi driver was hawking his services to us again. Comically, he remembered us and kept repeating "ok ok 50 riyals, 50 riyals" to us, but our driver was already on his way so we had to decline. I'd like to say we taught him a little lesson in free markets and dealing with foreigners, but I'm really not so naive...
