If a guy's got a designated driver, go ahead and let him get toasted.

Let them do it. Go right ahead.

Make sure there's a designated driver or get a cab. Never drink alone or on an empty stomach and don't drink to get drunk. People say that takes the fun out of drinking but that's the rule that psychiatrists and substance abuse programs use.

The real driver has been Jenny.

One commonality with modern celebrations is that they would have a 'designated driver' who was supposed to stay sober throughout the event to make sure that others were taken care of.

Just follow the rules. Always have a designated driver. Don't be doing anything to make someone mad. And just walk away from the trouble.
