What should be avoided during in-flight service when there is expected turbulence?

Serving hot drinks during expected turbulence should be avoided for safety reasons. Hot liquids can pose a significant risk to passengers and crew due to the likelihood of spillage during turbulent conditions. A sudden jolt or change in altitude can cause the hot beverage to slosh or spill, potentially leading to burns or injuries.

In turbulent situations, it is important to prioritize the safety of everyone on board. Cold drinks and alcoholic beverages, while requiring caution, do not present the same level of risk as hot drinks in the event of sudden movements. Using the cabin intercom is also a standard practice during turbulence to communicate important information and maintain order, making it less of a concern compared to the hazards posed by serving hot liquids.
