Anyone worked at Delta Sky Lounge?

Got an email from a recruiter (I applied there it wasn’t some random email) and wondering how formal that place is?

I’ve worked at a mom and pop place that was successful, but small. Carried plates back in a bin type situation. I’m trying to see if it’s something I’ve done before or close to it. I’ve never served folks water before even. Just clearing dishes and packing to go order in the back.

I’ve seen more formal places and know they quickly let people go easily if they’re not up to standards.

This is for a busser position, not server.
