When asked to create a decaffeinated raktajino in 2373, Quark claimed that "the removal of caffeine from beverages has plagued bartenders and restauranteurs for centuries! You can't expect me to solve it overnight!" Quark made this claim following his failed attempt to help get Major Kira off caffeine during her pregnancy with Miles and Keiko O'Brien's son. According to Chief O'Brien, he didn't want his son "to be born with a caffeine habit." (DS9: "Nor the Battle to the Strong")
