Sit down at the slot machine or table games
That is great if you are playing different games at the casino but even if you are done, you can still sit down at the slot machine or a table game to receive free drinks. Keep in mind that you do not have to play all the time to get the free drinks, you can just sit with your friends and witness them playing.
Keep an eye on the waitresses
You should be smart enough to keep your eyes and ears open while witnessing others playing. Observe the approach of the cocktail waitress on the floor keenly. Keep in mind that you need to be on your toes because the cocktail waitresses are quite fast as they have a large area to cover.
Wave at the waitress
You can wave at the waitress and give her a signal that you need a drink when you see her going pass your area or table. If you do not have an eye contact with her, you can loudly say ‘excuse me’ and get your drink by gaining her attention.
Most people get shy to ask for drinks, especially when they are not playing. Do not be hesitant and be mindful that there is nothing wrong in having free drinks at the casino. You should have a clear conscious and while you are asking for a free drink, you can give an impression to the waitress that you are playing the game, not just sitting idle.
However, you must not go overboard with having free drinks, as it may end up in embarrassment.
