Annoyed Cashier

I was at the your Jabulani branch yesterday and I must say the service was appealing. My debit card declined because if a minor issue where I advised the cashier that I just had to check my banking app and transfer money to this account to where I will then make payment. I was with my 2year old grandson and had to find a seat to sit. Whilst I was busy with my app the cashier came to me and tapped me on the shoulder looking and sounding annoyed saying we need the money. I told her I was done and that we could now make payment. Needles to say our food was also not very well prepared I didn't want to still sit and eat even after I advised that it was a sit in. First and last time at Burger King Jabulani mall
