Someone wanna explain to me the logic it not letting peolle use the bigger cups for free waters? Trying to save paper her so me and my wife share 1 cup but im bitched at because i filled 1 big one vs 2. So not only do I waste the water in the big cup I then sarcastically tell the lady do you want my cup back and im told to throw it away... so its a fucking waste either way? Theres no sign saying no big cups for water either.
