Gag.

This is bad.
I had an audible reaction to a table's gross table manners.

I'm serving a table of 5 and when their food comes, I notice the parmesan cheese container is missing a serving spoon, so I say to the table,
"Oh! Let me get you a spoon for the parmesan cheese"

I leave immediately, head straight for the spoons, and return within a minute only to find:

THIS GIRL IS USING HER FINGERS AND SPRINKLING THE CHEESE ON HER FOOD!
I'm talking, dipping her hand in the container that sits on the table all day, available to all who sit at that table!

I walked up, must have had a look of disgust and said, "Uhhhck. Um, here's the spoon."

Gag.

And, yes. I did change out the cheese after they left. Gross.
