The origen of cinammon

At the pet store today, I stumbled across TWO misspellings. Unacceptable!

Exhibit A: “Cinnamon” is spelled incorrectly.

Annnnnd, Exhibit B: They were able to spell “budgerigars” properly (I admit, I had to research to make sure they did!), but not “origin.”

An employee at this pet store walked around the corner just as I was photographing these signs. She didn’t say anything to me, but she (understandably) gave me an odd look. I thought about explaining myself but I chickened out. I’ll admit, I’m not as assertive as I should be. So I’m wondering, do any of my fellow grammar snobs point out grammatical errors when you see them in public places?
