How much is the amount that you put into your friend's account? I mean you know that you are transferring a huge amount of money. Why didn't you ask the limits of his bank including the amount of money that he can receive on a daily/monthly/yearly basis? That's being irresponsible on your part. Take note that you're transferring a huge amount of money (huge enough to make an account freeze), so at least put the limits into consideration.
I don't think it's irresponsible thou because it has happened to me several times and it wasn't always my fault. I see them (traditional banking system) as incompetent with their limit policy in the first place restricting people from accessing their funds. My first experience was very frustrating because I wasn't informed about the incoming transfer from the sender but the money was freezed until I had to go and update the account to increase the account limit. Even after the upgrade, it took almost a month before I received that money.
Bitcoin can never stress someone or giving you limit to transaction you could perform in a day. I had to go through my inbox after reading this, it doesn't matter whether it's huge amount or not. I searched my inbox and I discovered a lot of cases like that which usually takes them time to resolve. Unfortunately, one might lose the money if you failed to meet up with the requirements to upgrade the account.
