"Now; upon reading your blog; am wondering; do Muslim 'food handlers' here. . .working in dining establishments, use toilet paper? If not. . .should they not be working elsewhere; and not handling the public's food? Or is that Left-handers need not apply. . .?"
No muslim food handlers do not as a rule use toilet paper. They use water and their left hand and fingers.
Stay away from the ones with long or uncut fingernails.
I'll leave the rest to your imagination.
