If I'm not wrong, actually Maybank has the highest number of ATMs around town. So it might be practical to have a Maybank account (though their service sucks big time) where you put in your allocated monthly allowance in there, so that you'll enjoy the convenience of withdrawing cash anywhere.

Citibank:
Cute chicks/ladies at the bank branches, but I don't have an account with them. I do have credit cards with them though, so far so good.

Maybank:
I shall call them Maybebank. Mentioned above, I deposit cash because ATM convenience. Bank branch service is terrible.

RHB Bank:
Robin Hood Bank. Like one of the members mentioned, uplifting service can be done in any branch, base on this, one of the branch screw it up. They don't have user friendly cheque deposit terminal, unlike Maybebank and HSBC

HSBC:
There suppose to be hot banking officers, but there isn't much. From what I know, HSBC is short for Hot Shanghai Banking Chick. Nonetheless, this bank has work pretty well for me so far. Online banking, SST services are pretty good...like other foreign banks, lack of branches.

Standard Chartered:
Been to the Damansara Uptown branch, wanted to open an account. Slow. The staff looked like zombies...i told myself, "ah screw it, I'm outta there."

Public Bank:
For this bank, just take out the letter 'l' and the name would much better to suit its reputation. Been to one branch to do some deposits and counter officers are like 40 year old grumpy old women. Terrible attitude, one of the branch I been made me as if I'm in a pasar malam with IT Systems

Hong Leong Bank:
My first ATM account during my college. I remember there's this chick...ah well, Hong Leong never attracted me anyway.
