Discovery Bay doesn't have an official 'Xiao R' delivery/proxy service, but residents have created their own informal network:

1. WhatsApp Owner Groups: Most buildings have active resident groups helping each other with shopping

2. Local Supermarkets: Staff at Park'n Shop and Watsons sometimes help regular customers with errands

3. Property Management: Some management offices assist residents with basic shopping requests

4. Neighborhood Mutual Aid: Especially post-pandemic, residents formed informal proxy shopping circles

Pro Tips: Join your building's owners group, ask security guards, or speak directly with supermarket staff. The community here is quite supportive of mutual help.
