Coffee is out of your system by tomorrow morning. You can take black coffee home to meet your parents. You can make coffee as sweet as you want. You can smoke while drinking coffee. You can put out a cigarette in a cup of coffee.
Coffee smells and tastes good.
You don't have to put vinegar in your coffee. If your coffee pot leaks, you can use a regular paper towel. You can always get fresh coffee. You can turn the pot on, leave the room, and it'll be hot when you get back. They sell coffee at police stations.
