Ringing up in the grocery store today I asked the cashier to add a 16lb bag of ice, and the man behind me said, "16?"
"Yeah it used to be 20."
"16 is a very strange number."
"The 10lb bags are now 7lbs."
Man- "Of course they are because why should they use math correctly?"
Anyway I forgot my bag of ice and the cashier busted out laughing when I walked back in and grabbed it.
