* 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.
