Eh, most people burn their coffee or get shitty coffee. Salt helps enhance the coffee profile and decrease the bitterness that comes out when coffee is over brewed.

The number of people who don't know how to properly make coffee drives me nuts.

I think it's more of a tip for people who don't have a choice. Coffee isn't exclusively consumed for the taste.

I don't think they said they need to

Or get better taste buds

Many people learn to drink coffee, because it is a social thing to drink. Often when you get guests over, the first thing you offer is a cup of coffee. The bitterness of coffee is an acquired taste though. Not everyone likes it, so they add sweeteners and creamers to hide it.

I used to do that as well, but it got increasingly annoying when places ran out of sugar or milk. So I just decided to learn to drink black coffee.

Now I'm a snob about my coffee and my beans.

Maybe they like it that way
