お金と「ちょうど」の使い方 (usage of "chōdo")


What is the reason/meaning for cashiers to use ちょうど when accepting money?

> 500円ちょうどいただきます。

This I understand, since 500 Yen are a "round" amount. _"Exactly 500 Yen."_

> 812円ちょうどいただきます。

If I'm supposed to pay exactly 812 Yen, I understand this, too. _"Exactly 812
Yen, [as required]."_

What I don't understand is the usage when it's neither the amount required nor
a round number. Say I'm asked to pay 612 Yen and I'm giving 1,112 Yen to get a
500 Yen coin in return. The cashier will still often say

> 1,112円ちょうどいただきます。

Is it just the habit of saying ちょうどいただきます, or is there a different meaning
behind this ちょうど than _"exactly"_?




Actually, If there is extra amount, they should be using

> 1,112円お預かり(いた)します

because they are temporarily taking the amount 1112円 to calculate the
difference.

That said, it's hard to change the manner of speaking to suit with received
amount, and wrong usage will lead to some kind of impoliteness. So, I guess,
most people just remember most used one.
