In my days of working marketing, my boss always emphasized the importance of talking to decision makers.

If you’re dealing with organizations, you’d come across people performing different roles. Secretaries would often serve as “gatekeepers” who may limit your access to the key people to talk to.

This applies to a whole lot of things as well. There’s usually no point in arguing with clerks. If you have an issue with a purchase and can’t get any results with the clerk, knock it up a notch and bring your issue to the manager.

This works with haggling as well. Sales people often are reluctant to give you bigger discounts. Their commissions might be based on their gross sales so discounts would mean less for them. Take your case to the manager who might oblige.
