...some people just don't effing get it...
At a restaurant, slow time, one lady, local, late 30s/early 40s, is wrapping tableware in paper napkins for the lunch crowd.
Not once, not twice, but three times (just in the space of time I was there) she sneezes, does not cover her mouth, does not turn away, but directly into the tableware she is wrapping half a foot from her mouth. Wipes her nose with her hand and grabs more sets to wrap, grabbing with said hand the parts of the forks that goes in ones mouth.
This is why Kindness whatever Campaigns are pointless, there is just circuitry which a lot of other people have that is missing in these kinds of people that no kind of instruction will penetrate their thick skulls.
