Burger King — Employee rude service quality

Hello I went to burger king and ordered 2 whoppers 2 large fries 8 piece nugget and when I got to window to pay and get order he tried to give me 2 drinks I said politely I didn’t order any drinks he got mad told me I shouldn’t have ordered them if I didn’t want them and threw them into the trash tossed me a bag and slammed the window I tried to get his attention wile everyone was just standing around eating and talking and yelling to say I didn’t get the 2 large fries I also ordered. He said I didn’t order them I said yes I did he got mad again and tried to charge me again after I paid almost 30 dollars for my meal. All he gave me first was 2 whoppers and 8 piece nugget. He started fussing at me again and tried to charge me 9.60 for the 2 large fries. Told him I just paid almost 30 dollars already. He then said 3 dollars and some change can’t remember exactly how much I paid it anyway because my kids wanted them. I asked for receipt and his name he said it’s out of paper and he don’t have a name and slammed the window again. I must say there was absolutely no reason for him to treat me that way I did nothing or say anything to him to be treated that way. I have never been treated in such a disrespectful way like that in my life. I am absolutely not a mean person at all. I just trying to have a nice fast food meal for once in a long time I’m in recovery from cancer and thought it would be nice to treat myself wile I was having a good day. And that experience was very uncalled for. I don’t know if I’ll survive this cancer or not all I wanted was to try have a nice meal something different for a change. Absolutely no reason for any of that to happen to me. In no way was I rude to anyone there. I’m sorry for rambling on as you can probably tell I don’t get out much due to being sick with cancer and all.I’m sorry for complaining I just would hate to see this happen to someone else especially someone like me with cancer also. Thank you very much for listening. I really haven’t an idea of how to resolve my complaint I just want someone to be aware of it in case someone else has a similar experience like I had. Hopefully no one ever does.
