here you go...

[alrod]

I am confused a little with this phrase.
I heard it in a conversation when a man bought something at a buffet desk:

- I'll take coke and popcorn...
- Here you go... 4.50 please

The seller says it when the order is ready and the customer can go?
But he has not take a many yet!

I feel it is some idiom. Can you explain when the phrase is usable?

Hi alrod,
Here you go is an idom which express: "Here it is- here is your popcorn"

[alrod]

Thank you,

Can you give an example where I can say "Here I go" (they, it etc.)

[-x Here I go doesn't have any meaning. But after hand in sth to sb, you can say "Here you go"
