For one of my businesses, I recently discovered that I can't stand it when people ask me for discounts or give other signals that they're shopping by price. (I always turn them down.) However, I don't mind it when I put out a discounted offer and someone snatches it up.
My first thought was that this is completely irrational, and I must be a secret "control freak" - I need to feel that I'm in control of the transaction.
That may be one factor to a small extent (I'm not sure), but I suspect there's something else going on. The people who approach me asking for a discount, I strongly feel that they are not good customers to have, that they will be more likely to end up being complainers. I do not feel that way at all about the people who see a discounted offer and take it.
Best of all, of course, are those who see the regular price and take me up on it without haggling.
Do you have any insights to offer based on your observations and experiences?
