So my Bank Account Number ends with 1 and I had given my details to a person for processing some amount. He got the number wrong and put 0 instead of 1 at the end. After exchanging mails regarding the delay in processing , i got to know about the problem.

So i called him and said - "So i can see that you have got the A/c number wrong. Because you have set the rightmost bit to 0 and it should be 1. umm sorry , i mean - it ends with 1 and not 0 !"

He takes a pause and says - "Ohhh! Really Sorry about that. I will fix it ASAP. And your coffee is on me. Just consider it one's compliment! "
