Agreed, unfortunately there are people I know, that would complain about foods either not having enough salt, or anyone that thinks the food that tastes sugary is automatically good.
Need an example? A friend's 90 year-old grandmother I know has diabetes; she will always complain about the rice not having enough salt, or would want to have someone order pizza.
Another issue is that sometimes, when you look at the food labels on certain juices; they would put more sugar or salt than it tastes sometimes.
