Root Cause
Hong Kong dim sum (yum cha, 飲茶) etiquette: tap two fingers (index + middle) lightly on the table when someone refills your tea — the silent 'thank you' that lets conversation continue. Origin myth: a Qing emperor traveling incognito poured tea for his servants; the servants tapped fingers as kowtow proxy. Sharing dishes uses your chopsticks reversed (back ends) or a serving spoon — never chopstick-to-chopstick. Bill request: ask for 'mai dan' (埋單).

92% success Open the teapot lid (or place it ajar on the rim) when you want a refill — the staff understands the signal. Polite Cantonese 'm goi sai' (thanks) and 'm goi' (excuse me) are useful.

Dead Ends
Common approaches that don't work:
-
Stop the conversation to verbally thank the server every time tea is refilled
55% fail
Tea is refilled 5-15 times per meal. Verbal thanks each time interrupts conversation and is socially awkward. The two-finger tap is the established silent acknowledgment.
-
Pass food chopstick-to-chopstick at a dim sum table
70% fail
Same East Asian taboo as Japan — funeral-rite resemblance. Use the back end of your chopsticks (reverse them) or a communal serving spoon to transfer dishes between plates.
-
Call the waiter loudly across the room with 'hey!' or by clapping
55% fail
Hong Kong dim sum service is busy and proactive — flag down with a polite hand wave or eye contact, or ask 'm goi' (excuse me, 唔該) for service. Tap fingers for tea. For the bill, gesture-write in the air or say 'mai dan' (埋單).
