I need a parcel

There is this energetic Indian guy who goes into Subway ( for those who don't know, Subway is a fast food chain in America) . He says "I need a veggie sandwich parcel". The cute attendant asks, "Sorry, what?" and this guy repeats "a veggie sandwich parcel" with a sharp accent. The attendant politely and confusedly replies "I'll give you a veggie sandwich but for the parcel you need to go to the post office". This situation may be quite stupid for most of you, but you should know the usage of this word parcel in some parts of India. People walk into a restaurant and say "one masala dosa parcel" and walk out happily with a masala dosa. The catch here is that in the US people refer to take away food as "to go" and "parcel" means a package. In India, the word "parcel" is used in both the places. So this bubbly chap wonders as to "why the hell should i go to a post office to have take away food?".
