The interrogation technique to selling

The scene: A typical suburban shopping centre, saturday afternoon
Us: An innocent, fresh-faced young couple, flushed with the excitement of making our house nice, out to buy a vacuum cleaner
Our Nemesis: A spotty, pimple-faced youngster, with his school shoes and trousers on, in lieu of a business suit.
The shop: Godfreys, a shop selling nothing but vacuum cleaners.

We wander into Godfreys and stare at the wall of vacuum cleaners.
Salesman (aggressive pose): What d'ya want?
Us: Uh...a vacuum cleaner?
Salesman: Oh.
Us: So, you know, if you could show us some? What would you recommend? We only want a small one, we have a small place.
Salesman: You want bags or bagless?
Us: Bagless.
Salesman: Bagless? why?
Us: Uh, so we don't have to buy bags (etc etc)
Salesman: You still have to clean the filters, you know.
Us: Yes. That's fine. Can you show us some vacuum cleaners?
Salesman: Hmmm...bagless, bagless...(he stares around at the WALL OF VACUUM CLEANERS) hmmm.....oh. Here's one.
He has picked the one the highest up on the wall, which he cannot possibly reach without help.
Salesman: Well, here's a good one. It's bagless, and small. Here's the box.
He thrusts the box at us.
Us: Hmm...seems...nice...
Salesman: Yeah, it's bagless, and it's small, and light too. You feel how light the box is?
Us: Uh, yes.
Salesman: So I'll take it back to the cashier for you then.
Us: Oh, no. What are the features and such?
Salesman: What do you need to know? It's a vacuum cleaner. It's bagless. It's small. What else do you want?
Us: We want to make sure it's good before we buy it.
Salesman: Well, we can set up a model for you to try if you like.
He reaches unsuccessfully for the display model high up on the shelf.
Us: No, it's Ok. We'll have a think.
Salesman: Well, if you're not going to buy it straight away you may as well try it.
Us: NO. It's ok.
We hand back the box.
Salesman: Well that's that then.
Us: I guess so.
Salesman: Yep.

We walk out, trying not to fall about laughing.
