I understand that you may want to improve the efficiency of pickup, but I don't think it is appropriate to reduce communication with specific professional groups based on academic assumptions. The educational background of couriers varies, and regardless of the level of education, everyone deserves respect and basic polite communication. If you want to simplify the pickup process, you can： -Prepare the pickup code or order information in advance -Use self-service services such as courier cabinets -Maintain concise and clear basic communication (say hello, confirm the package, thank you) Effective communication lies not in the depth of communication, but in mutual respect and clear expression of needs. I hope you can treat people from all walks of life with equality.
