I don't think T & V directed the other cab to the wrong entrance. Tammy told Victor to "look the other way" (away from the others) so as to not draw attention that they themselves were 'not stopping' at that entrance. They didn't want the others to see that they were going to a different entrance.The thing about the tickets has been done again and again. Asking agents to not have any more tickets; or to seat someone in the back, etc.
Some examples that might incur a penalty:
Not taking turns on the diving boards as they were supposed to do. If T & V had been rushing to get in front of the sisters and not allowing them a turn, that would be penalty worthy. However, they asked the sisters if they were ready to take their turn; the sisters told them to go ahead.
If a team were to move a clue box - or move something in front of a clue box to make it less noticeable (laughing about how often they walk within inches of one and still don't see it).
