Back in UK I wanted to close my DXB HSBC account, I made the mistake of transferring all but a few Dirhams (no transfer fee) to my UK account 1st. There was a lot of questions about the amounts I had in the account previously and where they had come from until I ended up having to get my UK branch to sign over, in my presence, and internally post copies of the closure form . The remaining Dirhams caused a problem even after I suggested they give to charity, almost finally they posted me a cheque, in Dirhams but even now 11yrs later I get e-mails from them on general matters.
