ok! ill change old one to "the men"! thank you very much!!!

You're welcome. If you're at a bar, it might sound better to say "Don't give it to the men." This is because you are talking about the men at the bar, not all men in general. Also, you are probably talking about the men who are friends with the ladies, maybe their husbands or boyfriends, so "the men" sounds better.

thank you for your helps as soon as you read. its used for my working place where is bar! ill use it on my ads thanks!

Because "ladies" is plural, you would want to use "men", which is plural. And because you are talking about men in general and not a specific group of men, you wouldn't use "the" in front of "men". So I would say: Ladies' drinks are for personal consumption. Don't give it to men. I am not sure what the context of it is, but I think that is the best way to put it.
