What would you say to a person you caught digging their nose completly at a supermarket?

Nothing, because that would be rude. People have bodily functions that need to be attended to.

Admittedly, it's not socially acceptable to pick your nose in public, but talking to a stranger about what they do with their body is also rude.

That's why you wash everything you buy from a market. Wash your hands to stop the spread of germs. #EVERYTHING.

Watch out for the sharp toothed snail!!!

I would say, "Is that where you keep your money"?

'Gettin' anything good?'
