DOESN'T PASS MUSTER 🌭 | ENGLISH VOCABULARY

If something doesn't pass muster that means  it doesn't pass inspection. It's just not good enough.

For example, the other day I was  pulling dirty dishes out of my dishwasher that was  

supposed to have cleaned them and I said, these  dishes don't pass muster. I mean, look at that.  

Food.

That shouldn't be on a clean dish. What  does muster mean anyway?   

Muster is an assembly of troops. So when it doesn't pass muster that means they have not passed their formal  

inspection. Do not confuse this word, muster, with  the word, mustard. Which is completely different.  

Can you pass the mustard?

Thanks.
