I would settle for people not coughing an sneezing into their hands and then immediately touching everything in their vicinity. I see everyone around me doing this and it disgusts me.
(For the record, a better way to handle it is to sneeze into the inside of your elbow or immediately wash your hands after.)
It could be worse. Where I work, a few weeks ago I saw somebody lick his fingers and then reach into the container of forks and feel around for a while, apparently to find just the right fork.
I was guessing he had dry skin and had trouble picking up a fork unless he moistened his fingers first?
In any case I quietly went to a different container to get my own fork.
