What is the name/artist of this song?

I was at the Queen Mary, a drag club in Los Angeles, and one of the performers sang a song whose refrain went something like this:

You’re the luxury- that I can’t afford
Luxury- tell me (something something)

and then it would say “Luxury” over and over.

A guess would be that the song’s title includes the word “luxury” but a google search showed so many songs with that title I couldn’t tell which one, if any, applied to this song.

Does anyone know what song I’m talking about? The gist of the song was that the woman had been mistreated by her man, and was giving him the boot.
