Imagine you're a saleslady in the lighting department of a big store in town. Sales have been down recently so when you see a woman intently studying one of the floor lamps you go over to her and say, 'Can I help you?'
She says, 'I'm wondering how I would get this back to car park.'
What do you say?
'It's quite heavy and an awkward shape. I wouldn't want to carry it any distance.'
'It's not as big as it looks. It comes in half. And it's not really very heavy.'
Assume you say the latter. The woman then says she'll take it, oh, and she'll have a table lamp too. Do you point out that it's going to be a trifle difficult carrying a huge box and a carrier bag with glass lamp shades in?
Or do you tell herself she's a grown woman who must know her own capabilities?
Oh, and do you wait until she's paying before you point out that you don't have the bulbs in stock?
Do you give her as much as a second thought as she's struggling through town, banging into people, her fingers just about breaking by the time she reaches her car?
No, I thought not.
