Why? His iced tea is great. I even gave some to the libs in the office to try, but wouldn't tell them what brand it was. They all loved it, said it was the best tea they've had in a long time.
I told them it was Rush's tea. If they went and purchased it, I highly doubt they would fess up to it.
Because listening to someone selling tea is not engaging radio. He's got enough obscene profit breaks as it is. I tune in to radio to be entertained, not to listen to sales pitches for tea. I make my own tea. It's not that tough to do.
