got drinks in plastic bag

when we buy drinks, usually drinks served in bottle or glasse. but in Indonesia they sell it in little plastic bag with a straw in it. maybe will looks weird and bit disgusting for the first time. many merchant do this especially cold drinks that sold on the street. it seems you need time to adapt for this one. as long as the drinks are not hot drinks it might not be a problem, but if the drink is hot it can spilled on clothes. its not good idea.
