Spit the the cup

[Mvcode3]

This happened today at Starbucks in Tacoma. I’m standing in line at and theres only two people working and the line is growing long, older waspy lady in her 50's is in front of me ordering. The Barista is a 30year old black guy with dreads and sweet gold tooth. She takes like 3 Mins to figure out what she wants and takes another two to actually order it but is relatively pleasant the whole time. She pays and walks to the other side of bar area. As I walk up I see the cashier step back grab the cup he had handed to the dude working the espresso machine and proceed to huck a fat lugie (SP?) into it. He turns back to me with his fake starbucks smile and asks what I would like. I was blown away and unsure of my next move. Do I call him on it, do I still want this guy to be making my coffee? What’s my line?
