I have to say that besides many of Long Island's drivers, the people in the Radio Shack nearby aren't the brightest. While on my quest for 800 speed film, this was a conversation I had with a salesman:

me: Hi. Do you sell 800 speed film?
salesman: You're looking for a phone?
me: No, 800 speed film.
salesman: Oh, you're looking for an 800 speed phone.

We both walk down the aisle.

me: No. I'm looking for FILM.
salesman: I don't think we carry 800 speed phones.
me: FILM.
salesman: Oh, okay.

We walk down another aisle.

salesman: What do you use it for?
me: It's 35 MM FILM! You USE it in a CAMERA.
salesman: I'm sorry. We don't sell film here.
me: Okay.
