Learning customer's names increases the likelihood that they will return to your restaurant.
Politeness is another key skill for a cocktail server to have. Even if a customer is extremely rude to you, you should stay calm and remain polite to him. As you are most likely working with alcohol, you need to know how to handle situations when a customer has had too much to drink or when a customer who is under age wants to drink.
As a cocktail waitress, you also need to have good memory skills.

In other cases, you may be expected to mix the cocktails yourself.
