Burger King complaint: Extremely rude Employee

On 715 I stopped through the drive-thru to get some food and drinks before taking a hour ride home to where I live. I ordered 2 sandwiches, a fry, onion ring and a large drink. When I got to the window the lady handed me my food. I decided to ask for a large cup of ice to put my sons apple juice in. I politely asked the woman at the window who later told me her name was Jen if I could pay for a cup of ice in a large plastic cup. She told me no and that I would have to drive around again and order the ice separately. Considering she still hasn’t given me my large drink yet, I didn’t understand why she would tell me I had to drive back around the building for something as simple as a cup of ice. A few seconds later she opened the window again and asked me why I was still sitting there. I told her I would like a large cup of ice please, I’ll pay for it. and you still haven’t given me my large drink This clearly irritated her, she scooped a small paper cup full of ice and handed it to me along with my large drink and shut the drive thru window. I clearly asked for a plastic cup because with an hour drive home I know the paper tends to get soggy. I put the cup of ice back on the window ledge and waited for her to return. When she came back to the window she told me that if I didn’t take the paper cup she was going to call the police and shut the window and grabbed the store phone pretending she was calling the police. When she opened the window back up, I told her nicely that I was willing to pay for the ice and the cup and with all the arguing she is doing with me she could have already let me pay and sent me on my way. She then yelled FINE but you have to pay cash! I counted out $1.07 in change and handed her the money. She then handed me a Medium sized paper cup full of ice. I told her, that I needed a plastic cup. She yelled we don’t have plastic cups! I reached into my cup holder and lifted up the original drink that I bought which was a large and was in a plastic cup. The arguing went on for about 10 minutes, the people behind me in line were getting frustrated, one even pulled out of line. When she finally gave me the Large cup of ice she slammed the drive thru window. I beeped my horn so she can come back and give me a straw. When I asked for a straw she aggressively threw the straw at my vehicle. It didn’t even land inside my window, it landed outside on the ground which is dirty from people spilling drinks and god knows what else. I beeped my horn again so she can give me another straw but she refused too. She kept telling me over and over no, you need to leave! no you cannot have a straw you need to leave!
My boyfriend was pulled over with my son in the car a few feet away, he noticed what was going on and had to get out of his vehicle leaving my son in there by himself to approach the window and ask what was going on. I told him the situation and he told me to pull along side and he would get the straw for me. I agreed and pulled away. She then handed him 2 straws without a problem. This is extremely unacceptable for customer service. I’ve worked in the fast food industry for 8 years as a manager and I would never treat any of my customers with such disrespect ever! Words can’t even describe how upset this situation made me. Something that could’ve taken 1 minute or less ended up taking 10 minutes. I wasn’t even able to enjoy my food because this took so long everything in the bag ended up being cold! There is no excuse for any employee to argue over something so simple. Situations like this is how establishments lose customersbusiness.
