The disagreement is commercial, not personal
A showroom owner is buying presentation because customers form a view of their business from the driveway before they reach the door. A storage or trade owner is buying the lowest defensible cost because their customers never visit. Neither is being difficult and neither is wrong about their own business, which is why the argument recurs annually and never resolves through persuasion. Treating it as a personality clash guarantees it will still be running in five years' time.
What settles it is a decision made properly rather than a compromise reached informally. The committee chooses a level, the scope records it, and the owners who wanted more know exactly what was decided and can raise it again with a costed proposal. That is a considerably better outcome than an unwritten understanding that shifts depending on who last complained. It also gives the treasurer something defensible to say when an owner asks why the levy is set where it is.
