The Myth about Napkins

Today I was told not to fold napkins in front of guests in a restaurant. When I thought about it, I found it funny. Do people think that a machine folds them and magically resets the tables?
Think about it.... How sterilized is your napkin? How many people touched it, and were their hands clean?

It was washed by a linen company, then pressed in half a put into a giant stack of around twenty-five, and folded in half. Four of these stacks get saran wrapped together. This is one or two people.
The saran wrapped stacks then get placed into large bags by someone.
Someone delivers these large bags to restaurants on a weekly basis.
Someone else unloads these bags at the restaurant.
Server usually them fold napkins in large stacks. That is right kids, the same person that cleans up your dirty tissues, glasses, and plates, is the same one who folds up your napkin.
They do this in groups of two or more when restaurants are outside their peek hours.
These stacks of pre-folded napkins (or cutlery rolls) go onto shelves, and can sit there for hours or days.
Another server, bartender, or bus-person, takes them from here and places them on the table.
Then you sit down.
So, how many people did the napkin go through before you?
Why is it such a hidden thing in restaurants that servers should not fold napkins or roll cutlery in front of guests?
Are guest really unaware?

(The napkin cycle finishes by you using it. The server or bus-person places it into a large linen bag. The linen bag goes back to the linen company and the cycle starts again.)
