Starling is a word that people in Jakarta, the Capital of Indonesia, may have been accustomed. However, people from other region or overseas may be confused. You can't find the term in any dictionaries either.
The word refers to an abbreviation of two words coming from different languange. The first one is a famous brand and the later is Indonesian. The "STARLING" means STARBUCKS KELILING or in English means the MOBILE STARBUCKS.
Don't jump to a conclusion that the Starbucks has provided such service yet. The word does't come from them but from Jakarta's people as a nickname for mobile coffee sellers.
Usually, they use bicycles to crawl Jakarta's street. On their bike, they bring sachet instant coffee (definitely not from Starbucks) and water thermos. If you buy from them, they will stop in front of you and brew the coffee immediately.
Of course, the price is very cheap, only 1/20 compared to the "real" Starbucks coffee.
Here are the looks of the Jakarta STARLING, the Mobile Starbucks.
