about romancing Lane, you need to watch TV before going to bed in shift1 (so that you won't risk walking home in shift2).Or you can get dead drunk during Dare with Lane, and then Lane and BB will send you homeXDD
When in the coffee shop with Amelia, choose "something else" (whiskey), and reply to Lane's message in shift2 and go on a date with him, then you can unlock "Accept the dare" and drink your vodkaXD. After BB and Lane start arguing, you need to side with BB as much as possible (at least twice on BB's side), and you can get a drunk ending.
hope this is helpful to you<3
I'm not sure how much I can say without revealing too much information... All I can say is that the secret code is hidden in the explorable Mad Dog convenience store in shift2. Find it and do as spar0w says... remove the Spaces between words and put all the letters in lowercase... then use it as your name... Good luck to you sweetie<3
