Apologies -- I should've pointed out that I assume every venue will be doing the masks, deep cleaning, etc. So, if I were to edit my earlier post, I would say "all other responses being equal, I would choose the one with the tech 100% of the time."I would look at what the others are doing before making that decision. For instance, if the all the place with thermal scanning does is thermal scanning, and the other place requires mask for customers and employees, provides for social distancing, shows evidence of regular deep cleaning, perhaps will offer on the spot testing in the near future, etc., the thermal scans are of little concern or value to me.
fms point that someone can be very contagious and not show signs, including temperature, is true in entertainment venues as well as travel.
And again, yes, not every person who is sick has a fever. But someone with a fever nearly always has an infection, so having the ability to detect those folks is always a plus and never a minus. m
