How do y'all deal with arrogant people?

I was at a lunch organized for our office folks, and there was this guy sitting opposite me who kept going on and on about all the hobbies he has. He wasn’t just casually sharing—he was almost bragging, making it sound like he has this super tight, well-planned schedule packed with activities and also he was acting know-it-all and undermining what others around him were saying. At one point, even they stopped engaging in the conversation.

Now, my friend had asked him this question and him responding him personally, that would've been fine. But it felt like he was announcing it to the whole table, like the lunch was meant to celebrate his achievements, he tried to be loud and clear so everyone could hear him. I’m not sure if I’m just being jealous, because I have hobbies too and I’m pretty good at them, but I don’t feel the need to constantly talk about them or show off.

Honestly, I was cringing the whole time and just wanted to leave—I couldn’t stand it. Sure, you could say I should’ve just ignored it, but I want to know: are there better ways to handle situations like this?
