i saw this in the toilet stall at o'hare airport in terminal F. it's a new way to protect your ass while sitting on the seat. here's the directions:
So wht happens is that you wave your hand in front of this sensor with the number "96 on it".
then a plastic covering on the toilet seat rotates around, so you sit on a new plastic covering.
then the sensor displays the number "95", which i guess means that there's 95 plastic coverings left for this particular seat.
seems like a lot of work for a men's toilet. and it makes me wonder what the hell goes on in the women's shitter at o'hare.
seriously, what goes on in there?
