GUYS!! Why did he look down to my stomach?

So I was supposed to stay at the front watching the customers and as I head towards the back to check on if the order is ready my boss stops and asks me where I'm heading to and I tell him that I'm going to check if the order is ready so then I see that he looks down I'm assuming my stomach but I don't know why, I'm skinny tho and all of us have the same uniform so I don't know why, then I see that he kinda made a fake frown you know but why what could it be?
