No...they can't be shared, as it has your name on it and they compare that with your S&S card. You can present the card at any bar or in the dining room and get a soda. What I usually do is hit a couple of bars and get 2 sodas depending on if someone else that's with me wants one too
there are ways to get around the one soda at a time rule..just use your imagination...lol. Hope this helps.
