I don’t understand this at all. But I’ve never worked retail, so I have no frame of reference. Same with the “customer is always right” mindset. Nope, some customers are just cheats, or liars, or idiots.
I’d love to do this, but my spousal unit would have kittens. It’s a constant fight with him about bringing in topsoil and reseeding the whole yard. I figure if it’s green-ish and doesn’t sting, prick, or give me a rash, if I can mow it, it’s fine. But I would prefer a field of wildflowers.
I don’t know if this is so much a custom, but the whole notion of negotiating with a salesman when buying a car is stupid. Don’t waste my time - give me the bottom line. I will accept or reject it according to my perception of its value. We can conclude business in a matter of minutes. And don’t give me that crap about having to talk to your manager - I’m not going to get desperate or change my mind because you leave me sitting in your office alone.
If this isn’t a custom, then I apologize for cluttering the thread with it. But it’s still a practice that needs to go away.
