Web alarm clock for 8:31 a.m.
As you hand the ice delivery over to the next person at the public market, set the alarm for 8:31 am so the changeover does not drift. That leaves a clear checkpoint before 9:00 am for confirming which sacks have arrived, which stall receives them, and who is responsible for the remaining trip.
A noisy market can bury an alarm beneath engines, trolley wheels, vendors, and customers. Raise the volume enough to be heard from where you will actually stand, then play a quick test while the surroundings are active. Keep the phone close instead of leaving it inside a bag or vehicle. The ice delivery could be missed if you close this browser page or let the phone sleep before 8:31 am, so use the phone’s built-in alarm as backup when you may move away.
Before passing responsibility for the ice, have a little water and choose a light merienda only if you need one; something simple such as pandesal or a banana is less awkward during a busy handover. Leave a full breakfast or a hot drink until the receiving person knows the quantities and destination. With 9:00 am approaching, keeping both hands free makes it easier to check the load and explain the route without rushing food.
