Poor customer experience

I went to Burger King inside Promenade Mall. I’m not expecting classy restaurant treatment but the lady at the till lacked every aspect of customer service. I ordered and after done paying this lady goes and does something else and I’m thinking probably there are no receipts then I proceed to take a seat then she calls me to come take my receipt after she was done with whatever she was doing. I have never been disappointed because I have never been serviced like that at any Burger aking.
