Bad service

I went to McDonald's Birch Acres in Tembisa on Friday afternoon with my kids. I was using the app to reedem a deal, as always the cashier had to call someone else to assist with the reedem. As I was waiting for that person an email came on my phone, then the lady arrived. She said to me without greeting " let me see what is it, show me on your phone " I told her to wait just a few seconds for me to go back to the app and I was told to move away from the paypoint for them to assist other serious customers, and I refused. It took less than a minute for me to go back to the app and finally placed my orders, one was eat-inn and the other was take away, and was told to pay for them separately and I did that. Then took a seat to wait for my order. Waited over 30 minutes then I went closer to the collection point, then 10 minutes later I looked at the screen and both my orders were ready for collection. I went to the guy who was there to help me get my order, and he said he already knocked off, the other guys will assist me. Continued to wait while the guys were just finishing up with the other customers. Some other guy came and said without greeting me "give me your receipt" which I did. That area was a bit chaotic as staff didn't seem to know what they were doing, heard a guy assisting another customer asking his colleague to bring him 2 juice so he can finish with the order, his colleague asked him which flavors do you want and his response was " it does not matter what flavors you bring, these things are for kids and what do kids know about flavors". And the customer commented that she did ask for specific flavors. Then the guy who took my receipts came back with 1 order which was take away and went back again and came with my eat-inn order but it was incomplete, was done as take away. Then I asked the guy to change it to eat-inn, he just put a tray on the counter and said " take this tray cause you want special attention". Myvisit was just unpleasant, got bad attitude from the crew ( without name badges) including their manager. I asked him to call his Manager and he did "come this side, there's customer who wants special attention" was his exact words. She came and corrected my order.But my overall experience was just bad and my afternoon time with my kids was spoiled.
