Been here a few times with very widely mixed results. My most recent visit involved me watching one of the donation room workers take a pair of scissors and bash the handle end into a sensor to try and get it to work,
This happened at least 4-5 more times with yet another worker coming to hit the sensor on the machine. Meanwhile, here I am hooked up to it the entire time becoming increasingly nervous with a needle in my arm that these workers are literally banging this machine.
The screeners do a good job, but the donation room workers look exhausted and irritable.
