As someone who was in a service role and subject to an opt in post interaction survey, I don't believe systems like this are effective. They select for Karens with unreasonable demands. They use the survey to retaliate against the employee by leaving bad scores.
Yeah, I think the ridiculousness of the Uber/Lyft rating system (anything but a 5 means the driver should be fired) tells us that customer feedback of this sort is less than useless.
