Can We Learn From Abam!

Abam went to ECG to settle his electricity bill. He was told it was 100. He gave the teller gh1 and asked for a receipt. The following day he again paid gh1 and asked for a receipt.

He did this for 10 consecutive days until the ECG people called him aside and in anger asked "Do you know how irritating it is for us to give you receipts of just gh1 daily?

Why not just give us the whole of your balance?"Abam laughed and replied "That is exactly how it feels when you give us power for only two hours every day."
