We were on descent coming into a busy center/approach area with wx. We asked for 5 to 10 right for a small area of wx no more than 3-5 miles in diameter. The response was “everybody’s going through that you’ll be fine.” Couldn’t get another word in and wanted to respect your airspace by not deviating on our own. We clearly knew this weather would not pose a serous threat to safety but nevertheless we didn’t want to fly through it by choice. We encountered 30 seconds moderate turbulence that could have been easily avoidable. I have been thoroughly impressed with ATC for numerous reasons. This one left a bad taste in my mouth.
