The lady at counter number 2 deposits.

I went thee this morning to make a deposit my number was A007. I was sitting aaand awaiting for my number to be called and i realised that the guy who came after me was being served. I went to enquire why was that guy attended to before me as his number was A009 clearly he came after me. O was told to wait they will serve me aafter him when I asked why was I was there before him the lady just rolled her eyes as me and this guy were arguing and instead she continued to attend the guy and no apology nothing.
