Each trip must have a singular reason for why you’re taking it.
I used to live in the big city. Wanting more peace and quiet I moved out into the countryside. My work1, friends and family were still in the city though.
Naturally I took regular trips2 to the city. And while there, I might as well get some parts from my old bike store, visit this or that person, stop by at work, go to this event, get groceries from the specialty stores (Asia, Turkish), etc.
