Are barefeet dirtier than shoes?

Why can’t we walk into a restaurant or grocery store barefooted?

Hmmm. I was thinking….You know, if we step in dog poo with our barefeet, we know it and wipe it off. If we have our shoes on, we don’t know until until sometime later when we smell it.

You probably wouldn’t stop on a cock roach with your barefeet, but you would with your shoes on….
