Little Old Lady (LOL): I'm looking for a pet.
Pet store clerk (PSC): what kind of pet are you looking for.

LOL: one that I can spend time with and enjoy.

PSC: that's not much to go on. Do you have anything more specific in mind?

LOL: No. Your job as a pet store owner is to find the perfect pet for me. I don't want to limit your suggestions by saying too much.

PSC: well, here's a puppy. He's a lot of fun.

LOL: no... I like the tail, but that's all I like.

PSC: How about this kitten?

LOL: No, the ears aren't right and I thing it has too many colors in its fur.

PSC: Well, brown and white are technically only has 2 colors, so you want a single color.

LOL: Not necessarily.

PSC: Here's a plain white kitten.

LOL: I think I've changed my mind on the tail. Also, I'm not sure I want a pet that vibrates when it's happy.

PSC: Have you considered a hamster?

LOL: I'm not sure. Can you show me one so I can get a feel for it?

(PSC goes to the back and comes back with a hamster)
PSC: here's a cute monochromatic hamster.

LOL: I appreciate your trying, but your aren't very good at selling pets.

Pet Store Clerk #2 (PSC2) walks up: Hey, I have goldfish over here.

LOL: Perfect!
turns to PSC: You could learn from PSC2 about customer service.
