I added salt to my coffee for a few days without noticing. We were on vacation in a flat we rented. Usually I drink tee, but this year we had a new Senseo coffee pad machine with us. So I just started drinking coffee and so I used to add a bit of sugar and used the sugar cup standing in the kitchen. It was just a few days in our vacation when I noticed that some funny guy who rented the flat before us exchanged the sugar with salt.
I have to admit that it didn't taste bad. It wasn't just that sweet that I expected. And this was why I finally noticed: I added a bit more of that "sugar" and then it was awful.
