There's nothing more maddening and frightening to a sales or service organization than a client slashing away at your commission because you're making a lot of money. The only thing worse, I suppose, is a client trying to cut you out altogether because he thinks he can do the job better himself. Variations on this theme happen hundreds of times every day across America.
Someone always thinks brokers earn too much for too little.
It happens to salespeople in the field who develop a barren territory into a goldmine, only to see their commission structure cut in half or their territory divided. Someone always thinks your profit margins are coming at their expense. These situations are a good argument for maintaining trust in business - because the start of any lasting relationship is trust, not suspicion. Unfortunately, there will always be people with short memories who can't help putting you between a rock and a hard place, no matter how much you deserve their trust. Tell them everything every time.
