happy to chat... ping me @davemcclure.

if it's really the case that none of your staff at all of your nightclubs / restaurants have these issues, them I'll eat my shorts & buy you a beer (either way, I'll buy u a beer in fact ;)

certainly it's been my experience that technology used to improve efficiency may not always be appropriately / perfect, but in MANY use cases where I've had to wait or choose from confusing menus, I can't imagine how it wouldn't help.

however, I'm open to hearing why I'm wrong if you have data to back it up.
