The facility I worked at has hand geometry scanners for accessing the protected area after going through security screening. You put your hand on a pad and the computer compares your hand shape to one stored in memory, along with swiping your security badge. I hated them. Enough of us finally prevailed and they put hand sanitizer stations on the other side of the turnstiles, but I'd walk to my office and immediately go to the rest room and use soap and hot water.
Royal and the others could at least use a sanitizer brand that does kill norovirus. There are some out there, yet they all seem to use standard Purell, and I think it gives a false sense of sanitation to guests. It would not bother me if cruise ship buffets had servers all the time and not just when they realize an outbreak was happening.
