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.
