No Tony they dont.
But this is a retail shop where "profits" matter.
By kicking up a fuss and putting customers off buying products "hurts" them more.
But I don't want to "hurt" them - I want to get my way. And I can do that by being cooey-wooey, & out-thinking them.
But it's each to their own. Some do the shouty thing, others do the talky thing. My best results come from talking to folks in a civil manner, & treating them as equals.
"We have a problem" - the word "we" specifically - is like smiling - it's amazingly effective, completely free, & generally gets the job done. Whereas "I have a problem", or "YOU have a problem", starts everyone off on the wrong foot, & almost invariably kills any hope of a successful - by which I mean, "I win" - negotation.
Patience, persistence, politeness. Amazingly powerful.
