Not useless.People seem to forget that any one of us could be an asymptomatic super-spreader. So the temperature checks and the survey questions are pretty useless.
Each layer of protection has some holes in it. When those layers are stacked on top of each other some of the holes in the layers are covered by the layer above or below.
Temperature screens are just one layer. Social distancing, frequent hand washing, not touching your face, properly wearing a mask, etc. Each one by itself only helps a little. Combined they potentially help a lot.
