I’d be more worried about being poisoned. Who is giving away free sandwiches? Ya’ll far too trusting. Zero trust is the only way to go.
Do you trust your neighbour with your spare key?
Do you trust your doctor with your medical history?
Do you trust your pizza delivery guy to deliver you pizza's that aren't poisoned?
Being skeptical is sometimes a good idea, like when it comes to "online research" or "alternative medicine". But having zero trust in even the most basic human interactions sounds like hell.
I don’t trust most Doctors either, and you probably can’t trust any medicinal organization with keeping records confidential, plenty of examples of breach of that trust.
I think you are not skeptical enough.
