Please translate in English: This joke

I went to the supermarket to buy something today, and my friend asked me to help bring some food.

I asked him what he wanted, and the guy said: "Whatever, it's best to bring something salty!"

So I went straight to the supermarket and searched the shelves but didn't know what to buy. Finally, I brought him a bag of salt back
