Take It With a Grain of Salt

An incresing number of restaurants are taking the salt shaker off the table. It seems that it angers the chef when the person eating the food determines how salty they prefer the food. Fine, then let the chef pay the bill when I find that I would prefer additional salt when there is none available. As an aside, I have never been refused when I have asked for salt to be delivered to the table. Why the charade?
