Kurnai mate,
Its exactly the same over here in England.
If you haven't got the latest plastic rocket and a wad of notes hanging out of yer arse pocket they look down their nose at you.
I have a 1997 XJ600s divvy and I wouldn't take it to a Yamaha dealer even if you set a rottweiler on my knackers.
They ought to remember that once the warranty runs out you can take it anywhere.
I take mine to a little bike shop about three miles away, they strive to get parts in a few days, have reasonable service costs and above all are bloody nice folk.
My advice mate is take it to a non franchise dealer, they will be more grateful for the custom and probably treat you better.
All the best
