Why do companies think only men have IQ to handle financial tasks?

or for that matter anything that requires use of brain. It happened today again but with another financial institution. I was chatting with a representative, greeted me with Ms X and two message down calls me sir. I am not asking too much just right salutation. And this has happened often to me and it is so frustrating. Especially when realization hits that these people actually think these tasks can only be done by men cause women don't have brains so let's just call them Mr. or sir. Men feel uncomfortable if you get their salutation wrong and they would spare no chance to show displeasure while women need to get used to it. I am so tired of this.
