When was the last time you had a milkshake? Even if the answer is "five minutes ago", then obviously you're due for another! Having a bad day? Just grab a milkshake. Angry or tired? Take it out on a milkshake. Hungry? Enjoy a milkshake. Traffic jam? Go get a milkshake or five. It works wonders.
It doesn't matter where you have it.
You could have it:
On train tracks, even if it's unreasonably cold!
