I work evenings as a barista serving coffee.
Yummy, ever worked with espresso? I love espresso!
Why yes, the majority of the drinks that I make are espresso based.  It's delicious.
What kind of cream usually goes in coffee? Where I'm from we mainly use whole milk.
We use a variety.  Whole milk, cream, and soy milk.  We will steam or foam it.
Do you prefer blonde or dark coffee beans? Or are there other kinds of beans too?
Coffee roasting
Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste. Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard and other chemical reactions that occur during roasting.
The vast majority of coffee is roasted commercially on a large scale
many consumers find comparable with what is available in current espresso bars. This assessment may be in part due to the lesser frequency of proper barista training by many coffee vendors.
The Telegraph noted in an article that Starbucks had temporarily closed some of its outlets to retrain baristas, citing problems with barista preparation of espresso drinks and poor practices such as re-foaming milk or calibrating pressure for non-optimal brewing time. Pod manufacturers note that these problems are generally reduced by the use of automatic machines and pod technology.
