The attendant, a middle aged woman that I see everyday except Saturday, was talking loudly with a 20 something year old when I walked in. Clearly talking about the vax and I hear her say "It's all fun and games until somebody gets polio."... Mmmmkay

So I gather my items and while she's ringing me up she tries to initiate small-talk by saying "I think I made him laugh"...

Me: Oh?

Her: I have a saying for the anti-vaxxers 'It's all fun and games until somebody gets polio.'

Me: Oh you got the experimental vaccination?

Her: I had my second one yesterday and I feel like shit.

(Knowing that I have no chance to educate her on the declination of diseases due to improvements in sanitation...)

Me: Do me a favor and check the site with a magnet and see if it sticks

Her: scoffs

Me: Well, I'm in here everyday. Sunday you can either call me "crazy" or ask me "WTF?!?!" Feel better.

A couple of other people heard the convo. I'll bet she tries to find a magnet as soon as she can find a few minutes. I'm going to start carrying one in my pocket. Will report back.
