Re: What would you do?
I'd go to the other shop to see if they have a 490 and cast it. If that's the rod, buy it from the original shop because your mentor Steve put one on order for you. If not, then let Steve know and see if he can make a change to the order.
Since you said you know the owners, I would have a conversation with them about how you were treated in their shop. I'm sure they'd like to know because if this is happening to you, it might have happened to others. Acknowledge that you're a loyal customer (I'm sure they know this) but you're happy to take your business elsewhere. Whether it's the other shop or internet, there are too many choices these days to have to deal with bad customer service.
As far as Tim's behavior: I question how he's in a position to be a manager with such poor customer service skills, let alone thinking that a flagship model in a highly popular configuration won't sell. Add to the fact there's a good chance the order can be changed. Maybe the guy had a bad day? In any event, that's no excuse to take that out on any customer, let alone a loyal one.
