Oh! Sorry for the confusion, he delivers the drink to customers on the table in front of him, not to their table 🙃. There are five positions on the table and each customer is assigned a particular position. It would be so cool if he delivers them to customers as well. However, robot waiters are starting to become a thing in some restaurants now!
Ah! That makes more sense! 😀 Call me old school thow, but definitely prefer to interact with real people. Cheers! !BEER
