(Cover) - EN Showbiz - Demi Moore was stunned when a restaurant manager asked a worker run to a local store to pick up her favourite drink.

The actress was dining with her husband Ashton Kutcher in Beverly Hills when she requested a glass of coconut water. The tipple has high levels of potassium and minerals, and is often marketed as a sports drink. It can help raise metabolism and boosts the immune system, and is a favourite among stars.

The eaterys manager promised to fetch her the drink, before hastily sending another worker to fetch some as he knew they were out of supplies. Demi finally received her drink 15 minutes later, prompting her to laughingly ask if theyd had to get it in specially.

Actually... yes, the manager admitted.

Demi immediately asked to meet the man whod run to fetch the drink, and tipped him $50. Next time, it might be easier just to say you dont have any, she laughed. (C) Cover Media
