Hey there!
If alcohol is being served, you need to keep some important things in mind. Your first decision should be if you can handle the possible intoxication alcohol can give you, or drunkenness. It can impair even your basic functions, including driving. If you have to drive, keep that in mind. You could put yourselves and others on the road in serious danger.
Drinking can lead to alcoholism and those who do drink need to be able to make smart and logical choices before drinking.
Hope this helps!
