Report it or not, I would have still gone out, IF the benefits of doing so exceeded the cost. And how much? Until the marginal cost started exceeding the marginal benefit. If that was the case, they could trust most rational people, since not going out would have resulted in positive opportunity costs and deadweight.
However, if the benefits are zero, or exceed the cost right from the start, there is no way I would go out in field circus without its being a requirement. Every yoctosecond I spent out in field circus to appease Brother Hounder resulted in deadweight. Hence, waste.
