The most consistently found contaminant found on public keyboards is human feces.
Is that why I'm a crappy typist?
Thanks for sharing.
One time while having dinner in a restaurant, the woman at the table next to us picked her baby up and placed him on the table next to her dinner plate for some reason. The diaper was full, and a small lump fell out of same. She nonchalantly flicked this lump off the table, placed the baby back in his stroller, and continued eating.
For some odd reason, I lost my appetite, and have never returned to that dining establishment.
