coffee means I can take a shit at work

1. Coffee smells good
2. Coffee tastes good
3. Coffee is warm and comforting
4. Coffee is more socially acceptable than popping pills
5. Caffeine pills are somewhat harder to find. I can’t order them at a restaurant.

Edit: I’ll point out that you’ll rarely find someone who only drinks coffee for the caffeine. For many (most?) it’s just a perk, or even an unfortunate side-effect, hence the popularity of decaffeinated coffee.

On top of all the things said in this thread, I would also add caffeine is a diuretic. The liquid in coffee offsets that side effect.

I like the taste of coffee
