CUSTOMER: How does this work?
ME: What do you mean how does it work? It's a camera bag, you put your camera in it.
CUSTOMER: You just put your camera in it?
ME: That's what people tend to do with camera bags.
CUSTOMER: What about dust?
ME: What about it?
CUSTOMER: Wont dust get in the bag?
ME: Not if you keep it closed.
CUSTOMER: Wont dust get through the flap?
ME: Well, some will. But only if its really dusty. Where are you planning to take your camera?
CUSTOMER: Oh just the normal places.
ME: . . . .Right. We'll your camera isn't really designed for dusty environments, so best it'll be best not to take it to those places if you are worried about it.
CUSTOMER: I thought the bag would be different.
ME: Different how?
CUSTOMER: I thought it would be better. How do other people cope?
ME: It's not really a problem for other people.
CUSTOMER: I don't want dust getting in it when it's in my back pack.
ME: Probably be best to clean your back pack out then.
CUSTOMER: You're not being very helpful.
ME: I just don't know what you expect a camera bag to do.
CUSTOMER: Do you have any other camera bags?
ME: Yes, there is whole wall of them behind you.
CUSTOMER: How do these work?
