If you are having trouble remembering what customers you've
checked for IDs, listen to their greetings. Customers will
give you different greetings after they've encountered you
more than once.
If you can't remember where specific ingredients are located,
you can click their names in the recipe book to use them.
Don't waste liquor, or your boss will yell at you.
If you're within .2 or .3 ounces of the recipe, don't
bother dumping it.
