I'm going to advise that, in general, one should never try to replace the former sort of sentence with the latter sort of sentence. All the caveats are implied, people always speak from a personal perspective, all you're doing is weakening your rhetoric to no effect. The general form of the Umeshism calls attention to situations where errors of commission are invisibly expensive, and errors of omission are dramatic but not necessarily more expensive. Waiting in an airport lounge is wasted time, and it doesn't matter if you're waiting for the flight you have a ticket for, or whatever they put you on; if the objective is to minimize time in the waiting lounge, as why would it not be, it's just the total hours which matter. The opposite of an Umeshism is an easy riposte when they're being abused: "no, if you've ever been fired for being too wasted to work, you're not having fun, you're an alcoholic".
