I went into "Vomit" once for a fridge-freezer. I found just the one for me on display.
"I'm sorry, we haven't got that in stock, but we've got one similar that's £50 more..."
"Can't you sell me this one?"
"We can't sell that - it's for display."
"Cheerio, then."
Several months later, I went in for a telly. I found just the one for me on display.
"I'm sorry, we haven't got that in stock, but we've got one similar that's £50 more..."
"Can't you sell me this one?"
"We can't sell that - it's for display."
"Cheerio, then."
It struck me that they were putting things on display that they had no intention of ever selling, just to hook people in, before offering them a more expensive alternative. so I stopped going in after that.
