Am I in the wrong?

Soooo last week my husband went to his parents house to mow their grass for them. Afterwards, he had dinner with them and then came home to ANOTHER dinner that I had cooked. I have no issue at all with him eating at their house; I’d just appreciate it if he’d tell me so I don’t make a whole dinner that he’s just going to waste. Well anyways, he told me that he didn’t eat over there when I asked if he did. Today my sister in law tells me that come to find out, he actually did eat over there. Am I in the wrong for being upset that he lied about something so simple and stupid? Like just tell me you ate over there so I’m not waisting food 🤷🏻‍♀️
