Wouldn't this then agree to pretty much everywhere? There are bankers on every chest except in north west bar near lvl 1 wild at Varrock right?
Why not just remove bankers completely since there is the bank chest. I don't believe many people use bankers at all because of this.
There's few places where the bankers are quicker banking then the chest . Right click on banker and select "Bank" opens the bank without a dialog .
Also if u fishing sharks at fishing guild switch in ur settings to " mouse - one button" insted of the 2 button option , that way u dont have to right click (hold tap on android) while fishing sharks , also no matter on what u click chest or banker it opens up the quick options and just select "bank"
