S: Welcome to Canon, ma'am. How can I help you?
C: I'd like to buy an inexpensive camera.
S: Well, we've got several point-and-shoot cameras. These are all 35 mm compact cameras with auto-focus and a built-in flash. We also have these Polaroid cameras.
C: I don't think I'll need a Polaroid. Does this 35 mm camera have an automatic flash?
S: Yes, it does. But you can turn it off if you want.
C: Okay, I'll take this one. Does it come with batteries and a case?
S: Yes, it does. Here, I'll box it up for you.
