Our manager spread his flu bug to half the store and I finally got it a week later. Oh, I'm not sick. Cough, hack cough hack. No you are technically contagious until your last cough. I'm use to having no sleep nights and you just work tired but influenza sort of  crosses the line. I find if I just take a day off instead of working sick. That day of rest prevents it from going full blown. 

I also had to spend half the night chasing around my cat puking up hair balls left and right. So I got like no sleep.
