Last night work was stressful

There is a line out the door at Solstice and some small bitchy woman gives very specific, nonsensical instructions for her drink. She ends up coming behind the counter, and after a few minutes of bitching, she tamps some cinnamon and cocoa in with the espresso, and instructs me to steam more cinnamon in the milk.
Meanwhile, Emily is calling out a new order every ten seconds, and I get confused and pull the shots into a mug of water, and then steam the water. I realize my mistake and try to find the woman to remake her shots, but give up and move on to the next drink. I make more mistakes, and then can't remember how the espresso machine works.
