One thing about PIREPS of turbulence is some people haven't read the AIM and don't use the criteria published to report turbulence.
I have had severe turbulence twice in my 39 years of flying...knock wood.
So, you have to take precautions and a double call like bubbers said is the right thing to do.
ONE piece of advice I will give to fellow pilots is to make sure your seat belt is on TIGHT. IF you raise up in your seat in turbulence you will not be "ONE WITH THE PLANE" and you may over control or over react.
