I was once a Barista serving coffee at a coffeehouse in college.
Like Starbucks?  I have a friend that works for them and she really loves it.  Did you enjoy it?
It was a local spot. It was really fun. The word Barista is actually Italian for "bartender".
That's quite interesting - LOL!!  I wonder if people that speak other languages get confused and show up for a beer?!
Its never happened to me but I wouldnt be surprised. Barista is not necessarily a regulated term. Its just that most coffee shops use the title. 
Ah, I see!  Was it hard to learn all the different coffee combinations, beans, etc.?
Being a barista took a lot of training to not only know the drinks but to get them right. For example the Espresso, that is a real finicky beverage to get right.
I can only imagine.  I think I would make a mess of the whole thing!  But I am glad there are those that are good at it
If a barista is really good, they will do some latte art for you.
Is that like the ones that use the steamed milk to make designs in the coffee?  That is so very neat I think!
