Yesterday I edited three menus. Essentially removing their alcoholic drinks because they were not legal do sell off-premise. I uploaded their menu's using the single menu option.
I just had a customer who ordered beer from a restaurant that I personally had removed all items. Just confirmed it when I see it.
So the single menu upload, even though it says "complete", is not actually being uploaded. The full upload seems to take affect quickly. so I am now going to do a full upload so that way others don't order something not on the menu anymore.
I believe there was a problem with single menu uploads around the date of this post; although I'm pretty sure that was resolved some time ago -- give it another try when you get a chance.
