"Chai" means "tea", so "Chai Tea" is "Tea Tea".
"ATM" means "Automatic Teller Machine", so "ATM Machine" is "Automatic Teller Machine Machine".
Both are mentioned in the animated movie "Spider-Man: Across the Spider-Verse".
Except places are now offering Chai Latte Coffee so if you don't specifically order Chai Tea Latte, you could get some thing totally different than expected. I learned this the hard way.
Actually, in English, Chai does not mean tea, it means a specific flavor of tea. If you don't believe me, try ordering some Earl Grey Chai, see what happens.
