Today at work, a girl I work with oh-so-helpfully directed me to "be more on the ball".

Ya. Thanks. Clearly, I was making mistakes on PURPOSE and that helpful hint put me on the right track. And thank GOD she said it in front of a customer. I mean, I hadn't been so mortified in front of a customer in... well, my LIFE, actually.

So now that I've been corrected that, in order to improve my performance, I need to find a ball and stand on top of it, I have a very clear idea of how to succeed as a coffee bar attendant. Now I can die happy.
