Barrista!!! Ayiyayia!!!!

So...to make some money to pay off those horrible student loans and to keep my truck working, I got a part time job at a coffee shop. Never having worked an espresso machine before, I was nervous people were going to return their coffees. Acutally, a woman called me to inform me that I ruined her morning because I accidentally gave her cream cheese on the side of her bagel instead of humus. Please woman! If that ruins your morning, you have no worries in the world and you're pitiful for having to call and tell me that.
