What kind of person is this?

I’ve been doing Uber eats for a couple years now and once in a while maybe 1 out of 500 deliveries I end up delivering to a real weirdo. I want to know if I should be upset about this or if I’m in the wrong, and any comments are appreciated. So I picked up a semi normal delivery 8.5 miles for 12$, this person ordered 2 bean and cheese burritos, so I know order was correct because there were 2 burritos in the bag and I made sure to add extra sauce, took me about 3 minutes from accepting it to get to the restaurant but in those 3 minutes she was on me, asking for extra sauce, I’m like ok sure, then 30 seconds later asked me if I’m on the way, and how long till you are at the restaurant?, a total of 3 msgs. then after I get her order I’m driving straight to her but I stopped at a gas station on the way for 5 minutes tops, and right away 30 seconds after I stop she msgs me again “it shows you stopped” “why does it show you stopped?”when are u coming, I replied maybe 1 minute later telling her I’m 5 minutes away. 4 msgs in those 5 minutes while I was filling up. Then I went straight to her. The whole 8.5 mile delivery took me 27 minutes to make, food was still warm because I left right after they packed it up it was about 10pm at night. Besides the 5 minute stop I believe it was a perfect delivery. Anyways she gave me a dissatisfaction rating cause I saw it go down after her delivery and she also took her 4.5$ tip away. Obviously I will avoid delivering to this person, and if I accidentally pick up an order meant for her I still won’t deliver to her. But what kind of person just stares at their phone the whole 27 minutes of the delivery? And during time jars spams driver with msgs? Was she right to give me a thumbs down and tip bait for a 5 minute gas station stop, even though 8.5 mile delivery took me a total of 27 minutes which i feel like is very reasonable. Order was very simple so I’m sure it was all there. What are you thoughts?
