Banking

Stand near a banker and say any of these out loud.

Say	What happens
Anything containing bank	Your bank box opens. The word does not have to stand on its own: "bank", "open my bank", even "abankx" all work.
	(If the same sentence also contains balance, withdraw or check as whole words, that instruction wins and the box does not additionally open.)
balance or statement	The banker tells you your total balance.
withdraw <amount>	Pulls that much gold into your pack. Say the number straight after the word, for example "withdraw 500".
check <amount>	Writes a bank check into your box. Say the number straight after the word.

The banker has to be able to hear you: within 12 tiles. That is hearing, not seeing, so a banker on the other side of a wall still hears you and the box can open from the street outside. Right-clicking a banker and choosing Open Bank does the same thing without talking.

A criminal cannot bank. Wait out your criminal timer first.

Guild and alliance chat never opens the box, so you can talk to your guild about meeting at the bank without the window popping up.

The loose match is only on the word bank. balance, withdraw and check still have to be said as whole words. Check in particular is far too common a word to have a banker acting on it mid-sentence, and it converts gold.
