How can I confirm who it is when I receive anonymous milk tea?

There are several ways to confirm who sent the anonymous milk tea:

1. Pay attention to the package and label: check whether there is any information or label on the milk tea package. Some food delivery services will put the logo or contact information of the merchant on the package. If so, you can try to contact the corresponding merchants and ask them if they provide anonymous food delivery service.

2. Ask for help: If you suspect that anonymous milk tea is sent by a specific person, you can ask your friends, colleagues or family members for verification. They know or can provide information about possible milk tea deliveryman.

3. Social media survey: You can post relevant information on social media platforms, ask if someone sent you milk tea and invite them to come forward. Maybe someone is willing to come forward and provide relevant clues.

4. Surveillance video: If there is a surveillance camera near your residence or office, you can ask to see the relevant video materials to determine who sent the milk tea. However, please note that such activities need to abide by laws and regulations and respect the privacy rights of others.
