The title is self explanatory but I will contextualize it, I work in a factory where employees are forbidden to bring food, as the working day is 10h long and the employees only got 1h break/day, I think most people take something and eat in secret. Talking to an older colleague he gave the most obvious tip that it was just to put it in my pocket and eat hidden in the bathroom, but on my first day I went in with a small volume in my pocket (it was my toothpaste) the guard stopped me and asked me to remove it and show what that volume was for him to see and started saying that I couldn't pass with volumes, bags and blah blah blah. I'm thinking about taking a cereal bar or a banana but I'm afraid that they catch me, because I'm a bad liar and start to stutter.
