If it’s MY shrimp fried rice, I let her slide, with a brief remark about thievery. If it’s MY shrimp egg foo yong, I break both her arms and shove a pair of chopsticks where the sun doesn’t shine....at least in my mind.
We had a lunch stealer when I worked for GE; mine came up missing a couple times a week.
One day at home I took a burrito from my freezer and let it sit on my counter in its package for a couple days. Then I re-froze it and took it to lunch. Sure enough, it was gone at lunch time. Good news, though: No more stolen lunches!
LOL
