I don't really "hide" food... I love food too much to hide it haha. But at work, I do keep a few snacks like a small bag of cashews in my purse cos even though we aren't supposed to eat until break, I do anyway since it's sooooo far away (I work 7-3, my break is at 1:45-2 T_____T). I kinda shuffle away from everyone else and pop a cashew or two while organizing a shelf or something.
