You need one of these for your next trip, a snip at only $1,238.80.In theory it would work fine if everyone behaved the same. Alas people don't, which introduces that random element.
Trouble is, the system doesn't account for "ditherers" who loiter for ages trying to think about what to choose. It would work perfectly if people had a list and just took what was on the list and moved on.
IMHO better to avoid any sort of unnecessary contact.
