Because the boys aren't using it, it's the only open invitation Sombra needs to snag the full bottle of tequila they'd brought back with them - given as an 'appreciative gift' from the club's owner, but in reality, it's bought favors. Part of why Legionnaire's aren't allowed to accept more than small, small gifts or discounts. But what the Legion isn't actively logging? Sombra isn't going to tell them.

Tipping her head back, she takes a long pull from the bottle, already swaying in time with that rhythmic guitar while she leaves them to one another. The moonlight hitting ocean waves a decent stand-in for the bright lights of a club, sweat salt traded for sea salt and she only needs a tune to find a reason to dance, often as she's done it.
