我覺得 This truth 應該是指""If a company is already effectively on a par with its competitors because it provides service that avoids a damaging reputation and keeps customers from leaving at an unacceptable rate,then investment in higher service levels may be wasted, since(since後面可以不用管)..""一整句吧, 而這個狀況不適用regional banks managers, 因為他們根本沒有想辦法improve higher services
关键在于段1的最后一句"If a company is already effectively on a par with its competitors because it provides service that avoids a damaging reputation and keeps customers from leaving at an unacceptable rate,then investment in higher service levels may be wasted"中的UNACCEPTABLE RATE.原文说:若超过这个点,再投入服务就是浪费.而例子中的银行没有达到这个点(即,只是ACCEPTABLE),则它们还没有its investment in enhancing that service.
