Ugh..Sorry you're sick. This subject really gets me going.
Some people are extremely inconsiderate. I've had MANY people come in, or bring me their snot-nosed kids to get their hair cut while ill. Kids sneezing, coughing and wiping their nose on my freaking cape. I had one guy profusely hacking on my (once sanitary) work station and on the money while he was counting it to pay after telling me he has bronchitis. I asked if he was on antibiotics and he said no. Really!? STAY THE **** HOME! A haircut isn't a priority.
I keep a can of Lysol in my station. I can't stand people like this.
