Great tips. This is more of an opinion, lemon berry soda isn't that useless. I right-click and step backwards before Viktor gets catches me, it usually ruins his jacket.
In the end-game it is useless. You can not catch viktor like that. It is extremely risky and it works like 1/10 times. Just use the muffins from the staff only room. Also don't use any of them until the end of the game or something. (like7/10)
