It's time for you to leave. So you grab the food you brought and your remaining drinks, put them back in your bag and take them home.
No no no, you don't!! lol I would probably take home the pre-mixed alcoholic drinks, if you bought them for you and didn't consume anything else, simply because they are expensive and most of my friends don't drink Southern Comfort lol, but no, you don't take anything home with you.
