I went to see a doctor at the Walk-In Clinic yesterday evening. I woke up yesterday morning with green gunk in my eye. It turns out that I have pink eye and a chest infection. I have been prescribed antibiotics and eye drops. I asked the doctor if the pink eye was contagious and explained to him where I worked (at a grocery store). He asked when I work next and I told him tomorrow (which would be today at 2:00). The doctor told me that as long as I started the eye drops as soon as I got the prescription and had another dose before I went to bed, I should be okay to go to work and to just make sure that I wash my hands (we have Purell hand wipes at each register). By the time I go to work I will have had 4 doses of the eye drops. I'm still not convinced that I should be going to work. It's only a 4 hour shift and I'm already constantly sanitizing my hands. I've never had pink eye before, but I did work in a cafeteria and one of my co-workers had pink eye and she still came to work. Not sure what to do! 
Sad to say but my employers really don't care if your sick! My eyes aren't too bad right now. I will just clean them really good before I head to work. 
I wonder sometimes, if people realize that now they're going to touch the doorknob and spread their germs to the doorknob and then someone else is going to touch it. 
You're absolutely right!
