What I consider to be 'Bad' Sponsors

To be honest I get a bit fed up listening to stories of people who have sponsors who:

Change plans at the last minute. Or don't show up.
Are never available.
Say they are going to do stuff and then don't do it. Ie unreliable and flaky.
Cannot be got hold of on the phone.
End up talking about THEIR OWN STUFF instead of the Sponsees stuff.
Are totally inflexible.
Get pissed off with Sponsees when the approach they are using is partly responsible for causing friction. Ie blame the Sponsee instead of reappraising the method they are using. Hey don't get me wrong, all Sponsees can drive you NUTS, but by and large it is WRONG to always assume that the fault lies with the Sponsee. That's all. Sometimes a different approach is needed. A tougher approach, or a softer approach. It all depends. Again this is at the discretion of the sponsor. If you simply do not have time for constructing another approach, then you have no choice but to suggest they find a different sponsor.

I have a list a mile long !!! of (what I consider to be) bad sponsorship, but I have focused here mainly on:
Flakiness
Unmanageability
Basic inability to get to grips with the Sponsee.

There are very common complaints. But there are many others!
