Passive Aggressive Cookie Policing?😂

The family I nanny for often has sweets around, and in the past, they've told me I can take whatever I want. Occasionally, I’ve taken a couple of cookies when they were available (I’ve never eaten an extreme amount of their food or finished anything).

Recently, I noticed they moved the cookies to a more hidden spot (where I’m sure they assumed I wouldn’t be), but I found them and took one. Now, there’s a new pack in that spot with ‘17 left’ written on it TWICE. Are they just being passive aggressive about me not eating their food and don’t want to confront it? I’m aware this is silly and I probably shouldn’t have taken one after they moved them. ***the nk is a toddler and doesn’t have access to any of these cabinets
