I shall give a story from the opposite perspective-not as a driver, but as someone who worked with customers. During my three years working in the service industry, I found male customers to be much more tolerable than female customers. Women seemed determined to find something wrong from the start-they came in with the idea there would be a problem, then acted as if there were even if everything went perfectly. They were also extremely entitled and dreadfully rude for no reason. And they never wanted a solution-they only wanted to complain!
Of course, not all female customers were rude and some male customers were a*sholes, but generally speaking, men were more tolerable. Hell, one of my rare stories involving a rude man ends with another man confronting him over his rude behavior. Perhaps this is because men have a subconscious desire to protect women and, therefore, are less likely to act in a way that could harm her emotionally or physically. And perhaps women feel competitive towards each other and, because of that, treat one another like trash in order to assert their dominance. I don't know.
When I am the customer, however, both male and female representatives tend to be very nice, generally speaking. But of course, that is their job and I try not to be a bother.
Bah, this was quite longwinded.
