Yesterday morning as I was driving my husband to the flight line, I suddenly turned to him and asked, "Do you smell onions?"
Then the smell quickly passed... he couldn't smell it, but he did point out that at that moment we were passing by the galley. My guess is they were prepping the onions for the day (it was morning).
Through a building's walls and my car (the AC vents from the outside though. hehe) I could smell the onions.
And at my party yesterday I set out cheez-its and goldfish crackers for the non-primals... they smelled incredibly rancid to me. Gross.
