(AIO) Am I in the wrong here?

My bf (25) goes to pick up food for us pretty often. Some days my mom doesn’t feel like cooking and asks where we’re getting food from. Then she asks if he’ll pick up food for her too and send him the money, but she gets it from where we do. She doesn’t order anywhere nearby, she orders from the exact same place we do.

This is only the second time she’s asked this week and the past 2 months. The In N Out part is because if she knows I’ll be out of town she’ll ask if I’m willing to pick it up for her on my way back. I’m always willing to because it’s on the way and doesn’t cost me anything other than 10-30 minutes in the drive thru.

I understand it’s not his mom and he has no obligation but I also don’t see anything wrong with what my mom is doing. She’s not pushy at all. It honestly breaks my heart to tell her no and that he just doesn’t want to because it’s her asking.
