I was at your establishment today purchasing a delicious iced mocha with low fat milk when it occurred to me that I could never handle your job. I cannot imagine taking orders on that little head-set thingy whilst making change at the window and simultaneously working the cash register.
If I were forced to take a position such as yours, I would be fired immediately upon being discovered cowering on the floor hiding from the tiny sliding window weeping quietly.
Hats off to you, Mc Donald's Drive-Thru Person.
P.S. The iced mocha I purchased was not nearly as delicious as the iced mochas at the Rock & Roll Mc Donald's near my home. Clearly one must be working in the shadow of neon to make a superior iced drink. Nonetheless, good job with the multi-tasking.
