NatWest Bank plc in Bramhall, Stockport

The staff at this bank are very poor at customer relations 1 visited the branch on a saturday to change some £20 notes for £50 notes I was the only customer at the time the less than helpful staff member informed me she had only 4 £50 notes in her drawer would that be ok as I required 8 notes, I found it difficult to believe that they only had 4 £50 notes in the building, she could not be bothered to ask the person sat next to her or look elsewhere in the bank, I just found it annoying she could not be bothered to help me with my request I only use this branch as it is the nearest branch to me and only as a last resort I try to use branch close to work during working week, I would be interested if any other customers have a similar issue with this branch.
