I think this is just another case of nearsighted self serving behaviour from a retailer. I get this all the time - even with things the stores have in stock, they look at me as an unwanted pest because I cling to film. I hear a horror story every time I walk in, and its usually delivered with a smirk.
Just two days ago, my local Henry's store clerk informed me that they havve very little film becuae manufacturers are "not shipping it" - and made that face like she was about to call security...
Screw her - I told her that I like to support my local stores before they all go away, but with their attitude, I dont see the point.
This Nikon story seems like more of the same, that smirking little attitude that says: "So, what are you going to do now, huh?".
