A story from work

This is dated July 3rd.
Hello, and let me tell you all about the humans I've dealt with today (July 3rd). We had an all inclusive part at 7:30pm and then I heard that they were going to cancel it. For what, I don't know, but they wound up having it. I cooked the 4 wings platters and 8 fries. My coworker made the 4 pizzas for me. It was a big rush, I helped carry the food to their room. I mainly focused on cooking the meals. I had 2 ticket that said "All Inclusive Party" with whatever it is they ordered. This case 2 wings and 1 fry. I had a lady tell me to make the wings "well done." I was confused because she didn't have a sticker. She said her sister ordered them for her. I reminded the party host, who was taking orders that they could only order one thing at a time. This is so they can't order food for those not in the party. She told me she was just letting them get what they wanted so they would be on their way.
Apparently the lady who had ordered wanted to have an attitude because she kept saying, "Is there a problem? Because there shouldn't be a problem. He said we can get whatever we want."
The thing that bothered me was that I said there wasn't a problem several times, but she kept repeating, "Is there a problem?" After I said no several times. Keep in mind, I'm the only one cooking all the food and I'm trying to cook everything. Luckily, I spent most of the time cooking and not interacting with customers. But later at 9:24, the same lady came up and told me, "Your manager said we could get ice cream to go." She had an attitude the whole time with me. I was polite and even allowed her to get it even though it was passed time for their food orders to be free. Her food stopped at 9:15. I did ask the manager on duty what time their food stopped as I went to the back to grab ice cream cups. Just to double confirm that their food was over.
I got their ice cream and I put it in cups because every single time someone asks for ice cream to go, they mean a cup. This set the women off. The whole time I was standing there, trying not to say, "Fraulein, calm down. Do you need midol?" Because her attitude and temperament makes me feel like she was on her period.
I just remade the ice cream to placesate her and get her far away from me.
Have any of you ever dealt with people like this?

UGH! I actually remember this vaguely still. Lady was awful. Like I'm doing my job, don't go yelling at me for it. Just take a deep breath. I can tell by the way I wrote this that I was going to turn this into a video at some point.
