Sometimes the shop owner, or shop assistant (in places like for example Watsons, Guardians), they will whip out 1 or 2 newspaper to read themselves, then after reading they will put it back. Erm, some people go toilet dun wash hands one, some people go make choco cakes in toilet also dun care about washing hands, and assuming they have a higher chance to putting the read newspaper on the top of the stack, so you're indirectly buying a newspaper filled with virus and germs? I mean, I don't really read newspaper but I guess that's why people prefer to get newspaper from the middle of the stack or something. The top of the stack tend to be touched alot like if people want to check out what's in the news, they will take a peek first... so assuming they also go toilet dun wash hands, then...
