One of the local Mexican food joints (sit down place) has a manager who roams around with his shirt half-untucked but wearing a tie. He comes by and in a very friendly manner asks "how is everything." Splendid, but you're as sloppy as can be. Thanks for asking. If your physical appearance is important to your job and the bare minimum required is to have a shirt and tie, you better tuck it in or we will have to get all piñata on your ass.
