Put weekend errands in a sensible order
Group errands by area, do the stop with a deadline first and save cold groceries for last. Give the assistant your list, the neighborhoods involved and any stop with a closing time, and ask it to suggest an order.
What to check in the answer
Check opening times yourself before leaving, especially for the post office and library, since weekend and holiday hours can differ. The assistant's travel times are rough guesses that don't include parking, traffic or a stop that runs long. If the route passes a store you know gets crowded at a certain hour, adjust for that. Treat the order as a starting point.
What to do next
Confirm the post office's closing time on its official site or by phone, along with any other stop that has a deadline. Leave a little slack between stops if you aren't sure how long each will take. If you want to add or drop an errand, reply and ask for a new order.
