Coffee doesn't complain when you put whipped cream in it. A cup of coffee looks good in the morning. You won't fall asleep after a cup of coffee. You can always warm coffee up. Coffee comes with endless refills.
Coffee is cheaper.
Coffee never runs out. Coffee is out of your system by tomorrow morning. 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.
