professionalism for nothing but optics specifically drives me nuts. i work at a bank as a teller. i am not allowed to sit, wear shorts, wear sandals, wear sneakers, or have piercings other than my ears. how does any one of those things affect my job performance? in fact, standing all day without being allowed comfortable shoes (like SNEAKERS ) hinders my performance! honestly, if seeing the bank teller waiting on you sit bothers you, you need to get a life.
