Do you have a 'restaurant rule' that's outside of current conventions, but you strongly feel should be SOP?

Standard Operating Procedure

My rule is there should be two napkins. One for my silverware to rest on and one in my lap.

I do not want my silverware resting on the bare table.
Yuck.
The table rag likely wiped anything from the floor to baby vomit before it wiped my table.
