Listerine has on it's instructions the note
"do not swig from the bottle"
Now, if you've ever used a mouthwash, I'm guessing you swigged from the bottle. That's what you do. That's how it is used. By everyone.
Saying "do not swig from the bottle" is like Porsche selling cars with notices saying "do not drive fast or overtake in this product" It's like expecting an MP not to fiddle their expenses.
Why not just cut to the chase and have on the label "if this product doesn't work like we promised, well tough cheese as we had our fingers crossed behind our backs when we said it would make your breath smell better and your teeth last longer. Nah Nah Nah Naaaah stoopid!!!"
