Actually BG - HSBC (stands for Hong Kong and Shanghai Banking corporation) run franchises in this region (they have to under the 51% sponsorship regulations) and the service you receive in one country may bear no resemblance to what you experience elsewhere.

I remember a South African colleague who had come over from Abu Dhabi and she held an HSBC bank account there. She fully expected everything to be transferred over from AD but they would not do it saying they were not linked and were a local bank in their own right with very few links to HSBC worldwide, other than the branding and the name.
