"Protect Your Drink" coasters


"Back Off Jack--I'm Watching My Drink"

These coasters can indeed go under your drink, but better yet, they go on top of the glass, forcing the bad guy to use both hands or move it twice in order to dose your drink.  There is no perfect answer to preventing drink dosing (sometimes bartenders are involved, dosing for their rapist buddies), but these may help deflect the drug rapist from YOUR glass.
