Maybe he is tired of recalled products? Maybe he likes the Bio team that calls on him? Maybe the Bio rep is an excellent rep who he is happy to support? Maybe he took the time to learn about Bio and the quality products they make?
Seriously though, to whoever started this thread: Why did you start this thread? Why do you have an axe to grind?
Not everywhere, but in many major markets Bio is kicking ass, which means they are taking business away from someone else. Most likely they are taking business away from the folks who bad mouth Bio here.
Perhaps the reason you're hiding behind your computer and not talking s*it to anyone's face or publicly Bio-bashing all over town is that you know when your company puts you on the chopping block after one of their many infinite RIFs, or after one of their next recalls or after multiple quarters of watching your sales decline, you'll be sending Bio your resume, and you don't want to look too stupid to the Bio managers for openly being a hater, or to your customers if Bio happens to hire you.....
I'm fine with it if you want to do some Bio-bashing in my territory, since it will serve no other purpose than to make you look like an uninformed foolish child.
