NDA / CA - Non Disclosure Agreements / Confidentially Agreements

[Soleiman Bolour]

I connected with a broker last week and they asked me to sign an NDA. I was completely okay with signing an NDA, but asked if the commission would be paid by the seller or buyer. 

The broker got really upset with me and said, if you don't know about NDA's than you should go and consult an attorney to help you read one. 

Was my question out of line? 

Can I ask that the broker to write in if the commission would be paid by the buyer or the seller? 

Can I ask the broker to write in how many points they would want? 

Thanks
