I had the same problem twice, once at work and at the place where I lived at the time. I was in a share house for awhile. We shared all the benefits of a house, except you had your own food, room and toiletries etc. But someone kept take some of my food out of the fridge. So I became quiet accustomed to Cayenne Pepper on all my sandwiches and in some of the things I had in the fridge. Funny, my sandwich never got stolen again, and the thief at the house moved out. To this day I still eat Cayenne Pepper sandwiches.
Oh yea, almost forgot this one... I used to make up a bowl of popcorn, butter, salt etc. It was perfect to sit and watch a movie or game. But as soon as I sat down, the wife and kids would take my bowl and say thanks. So I went back and made up another more perfect bowl. Only to relinquish it to the family again. Not to be out done, I made up another perfect specimen of popcorn, more butter, and salt with Tabasco Sauce!!! The kids and the wife didn't take that bowl away or another bowl after that. Unless I made it for them. I hardly will eat a bowl of popcorn without the Tabasco Sauce on it.
