What do you mean by my bank? My branch? What would they know about me? I've been my bank's customer for over 30 years, but that counts for nothing.
I first opened an account or two at branch A, because it was the nearest to where I (that is to say my parents) lived. Then, when hunting for my first mortgage, I visted an IFA who was recommended by my solicitor through whom I was buying my flat. The FA seemed to have a "thing going" with the loans manager at branch B (near the FA's office but nowhere near my parents' house nor where the flat I was buying was), and I was encouraged to agree to move my account to the FA's cronie's branch, as this would "oil the wheels" of my loan approval and would obviously earn brownie points for the bank manager. All against my better judgement. Meanwhile branch B has been amalgamated with branch C, despite continuing to maintain a presence in both locations, so whilst my account is held at branch BC, I'm actually within walking distance of branches A and D (now that Ronald senior is dead I've moved back in with mother Nancy).
So branches A and D are the ones I visit, even though my account is actually kept at branch B or BC. The staff at A and D may or may not recognise me, but I wouldn't say the "know" me in any meaningful sense of the word, and neither really would staff of the branches B and C which I as good as never visit.
