There are many kinds of club, and there are many reasons to have a drink by yourself, most of which are not about anybody’s sorrows. Maybe you like the music, for example, but aren’t in the mood for company.

But if we want to assume Musk was drowning his sorrows, and that it’s an EDM dance club — this seems to be your implication, maybe it’s true — then I still don’t find it weird. Darkness, distraction, the desire to be among people but also alone, avoiding your entourage… plenty of good reasons.
