I have a double barrel name and for conveniance I only sign with the last part of my surname.
I originally registered at my bank with my full double barrel name, since there is not much room to sign the forms with a long name I sign with the last half of the name, slowly the bank has taken this to mean my double barrel name is a middle name and when I corrected them they said I need a name change form and depoll, I said but I haven't ever changed my name and on my visa card it say's the initiall of my first half of the double barrel surname, they have slowly lost the proof and when I told them that isn't my name, there is an error they said that is how I sign, well of course I sign that way, there isn''t enough room for a double barrel signature, the bank lady tore up the name change form in front of me and threw it on the ground.
You see I wasn't changing my name I was correcting their error.
I considered myself lucky to get my visa card back from the cashier that day.I was also told to [get out of the shop wer'e about to call the police.]
That was my town head branch who deal with me on a weekly-fortnightly basis.
