What the hell is Biden doing at a public beach when he's the supposed President of the US

What the hell is Biden doing at a public beach when he's the supposed President of the United States.. Shouldn't he be at a private beach with Obama or some celebrity..
If this was Trump... Hordes of people would be flocking towards him in adoration..But Biden.. nothing. Crickets..
Also.. Why does he walk like that?
It's like we're being psyoped on an unprecedented level. There's no other way I can explain this.
