Contacting listing agent directly - RE protocol

[Jim Stardust]

I have a broker that I work with off and on, she got information that I contacted an agent directly (I just needed very specific information on a property and didn't want to bother her) and she sent me a somewhat nasty email saying that I should have enlist her to do my DD, that's what she's there for, and that there are certain protocols among agents, etc. I haven't replied to it yet, I didn't tell the listing agent anything except that I wanted a couple of questions answered, so it's not like I'm going around her back to buy something with her knowledge, what am I missing?
