Worst advice given by a manager

There are great sales managers and there are bad. This thread is about the bad. I simply want to hear about a time where your manager really effed up.

One that comes to mind for me would probably be when I received a shitty unsolicited RFP from a prospect in the size of 15,000 employees. No access to decision makers and poor product fit. Simply waste of time.

So I go to the sales manager and say that we should decline this RFP as we're refused access to the right people and it doesn't look like a great fit for us. Again, waste of time.

The sales manager freaks out and says that we need to complete every RFP! He then calls the CRO to create an internal task force who ends up spending weeks on completing this RFP. As we go along the team members assigned from the different departments highlight that this is a really bad fit and shouldn't have been done in the first place. But the manager and CRO still pushes it through.

After completing it and sending through the client comes back and says they won't be moving forward due to us not meeting their criteria.

My manager then tells me to get back to them and offer the product with an 80% discount and says that they MUST buy for a price like that (wow). I refused and quit my job 2 weeks later as I couldn't work for a guy like that.
