Coffee is extremely important for millions of people to get pumped. Huffington Post listed some of the ways coffee drinkers prefer their caffeinated fix worldwide.

In Germany, alcohol lovers might want to get a taste of the Pharisäer. To warm their coffee up, Germans mix two ounces of rum in their cup of coffee. Topped with whipped cream, this mix includes dark coffee, rum, and sugar.

This might sound weird, but there is such thing as Egg Coffee in Vietnam. The ingredients: two egg yolks and half a teaspoon of condensed milk, vanilla extract and honey. This mixture will float on top of a hot black Vietnamese coffee, making it more like a dessert.

Austrians also mix coffee with egg for a cup of Kaisermelange (emperor's blend). This famous coffee blend is a mix of egg yolk, cognac, sugar and milk.

Mixing strong coffee with milk is popular in many countries.

The Gribaltar coffee originated by American baristas in San Francisco mixes the strong kick of double espresso and a smooth shot of steamed milk.

This blend is also a favourite in New Zealand and Australia. A drink called Flat White is also a mix of double shot espresso but with a little more steamed milk.

Partnering coffee with citrus fruits isn't weird for Italians and Mexicans either.

In Italy, a cup of espresso is often served with a slice of lemon on the side. The Espresso Romano tastes sweeter, highlighted by the citrus kick of lemon when rubbed inside the rim of your cup.

In Mexico, Cafe De Olla or "pot coffee" is a sweetened spiced blend. Mexicans slowly boil dark ground coffee in a saucepan with a quart of water, orange peel, cinnamon stick, and dark brown sugar.

These are some of the most interesting ways to make your coffee. For one coffee addict, however, getting free Starbucks everyday is way easier.

Baristas from Starbucks are hating on this one customer after finding out his daily coffee trick. The customer apparently bought 365 Starbucks cards and registered each for a different birthday. Through the Starbucks app, the cleverly evil person was able to get free birthday coffee everyday.

Although Starbucks baristas are already aware of this hack, they still couldn't do anything about it but to tell the world this isn't a very good job.
