****py service from waiters

I am a regular client buying smoothie fruit salad and breakfast, today the waiter went to the back of the queue and asked people behind me gave orders n after several orders she took mine I asked for 3 she put 2 breakfast got to the till had to wait before 2 clients that got there after me. I raised my concern but I was told that I didn't order, an apology for serving people at the back of the queue was not even touched. I was corrected for not saying my order with an argument. If that's client service, I will not visit the kiosk again. U have a start of the queue and exit but u start serving from exit and when asked u defend yourselves. Keep up the attitude and rotten service standard.
