Fair enough, I see where your coming from.
The point I was making is that a lot of people add salt without tasting their food. They've desensitised their palate to the taste of salt. Indeed, I think a lot of people have lost any sublety they once had in their palates and don't taste an iota unless it's salty as seawater. My mother, father in law and mother in law are all on blood pressure medication and they all add a shed load of salt automatically to anything they eat. I've seen them add salt to rashers!
I put a lot of effort into the food I cook. I work hard at it and I'm good at it. It's insulting to see the food seasoned again at the table before it is tasted. It might seem arrogant but I'm not going to facilitate someone to mess up a dish and thrash their health while their at it.
I have a special interest in salt and salt consumption as I've studied it and written some reports on it for some college courses I did in the past. Salt is potent stuff, particularly when it comes to health and it's abuse and that of processed carbs and fats is one of the major contributors to the ill health of a lot of our older relatives. I'm making a stand for the health of the nation in my own little way
