Good drink mixing is all about proportions. Two parts this + one part that = dancing with a lampshade on your head. Most package stores stock books or brochures with popular recipes. Employees can usually tell you what the hard stuff is made of thus making it easy to decide what to buy depending on your tastes. When in doubt, keep clear liquors and brown liquors separate and choose a fruit juice, soda, seltzer water or tonic as a mixer. When using a recipe, add the booze use a ‘pour count’ to make sure your portions are equal. This negates the need for a jigger. Anything you buy off the ‘top shelf’ is usually best over ice or on its own.
