How stupid are coaches?

[Terrapins Fan]

It's a rhetorical question, but really a serious one.

Here's the situation. I am doing a play off game. 1st round. Girls. The visiting team has an assisitant coach that I tossed ( my 1st eviction ever ) about 3 weeks ago. As we go over to shake the coaches hands, I am last in line (there are 3 of us ) I shake the head coaches hand and go to shake the assistant ( he shook hands with both of my partners ) and he pulled his hand away.... I always wondered was it me or was it him that was the problem. Now I have my answer.

Ever have a coach not shake your hand? I understand if it's because of illness, but this wasn't. I'd say I referee about 3 or 4 of his games a year....didn't seem like a smart move to me.
