a flight attendant stole my chicken

Was on a flight yesterday second to last row in F. Flight attendant asks if I want a chicken salad or chipolte wrap. I order the salad she comes back and said catering forgot to put chicken on the last two salads. I say OK not much of a choice

Couple of hours into the flight I go to use the toilet in Y to stretch my legs and see one of the FAs unwrapping a napkin with the exact same chicken missing from my salad. I know what it looks like because I saw the tray of another pax.

Thought I had seen it all...
