You fail to understand consent. Consent is not saying yes. Consent is meaning yes. It may or may not be measurable. If there are pressures that mean a person has good reasons to say yes when they do not mean yes, then it is not measurable. Consent that can't be measured must be assumed to be absent. Consent does not exist if a person is in a power relationship. The pressure to say yes comes from the fact that a guard, here, is in a position to dispense favour or disfavour.
