Courier's tips of fighting time

1. Eating meals while riding on electric bicycle. It is, of course, dangerous. But most couriers have tried this.

2. When delivering parcels to office buildings, take the elevator to the top floor and go down by foot. Waiting for an elevator wastes time and it may be full. Legs are more efficient: it only takes a few seconds to go down a flight of stairs. Chen has colleagues who walk down 40 floors.

3. Hold the elevator. Press the button to keep the elevator on the same floor while waiting for the customer's signature.

4. Establish a good relationship with the front desk of a company. When staff on the front desk agree to help receive and sign the parcels, it will save a lot of time of making calls and waiting for signatures.
