Tami Baribeau - The Bus Tour is test that we're currently running, and if it does well we'll be rolling it out to everyone. :) This is why some of you see the ticket in the top right of your screen and others do not.
If you click to help someone out by taking a ticket you don't actually GET a ticket, you're simply helping them fill seats on their bus tour. Once it's full, they'll post on their wall telling you to come visit their vineyard. Filling your bus tour gives the reward, which is why people are trying to have you take a ticket so they can fill their buses. :)
