Yeah some of them were TikTok. I don't know if it's gloating or recruitment tools, I'm just observing as a non-US person that's never seen perks even remotely similar.
And even if someone manage to share their actual work you likely will never see it because it's not something that goes viral.
It's the payoff for keeping the money printing machine running.
In WAT, prior to 2016? or so? we used to get a yearly surprise steak and lobster meal around the holidays. The date was never announced in advance, but one day in December you'd show up and there'd be fresh lobster and steak and fixings. Fantastic :-)
