Really husband?!

Woke up with a scratchy throat, 33w pregnant. husband is out getting an oil change. Texted him and asked if he could stop and get me a frozen coke on his way home...."there isn't a gas station on my way home so I'll see".  There's one maybe a half of a mile out of his way! Yes I realize this is a dumb vent but any others out there have SOs that really won't go slightly out of their way to do something for you??
