In the original SFM demonstration video for the Luxury Lounge (the workshop submission for which can be found here), the glass and its contents are translucent, but that isn't so in-game. This fixes that.

I get that the thumbnail probably doesn't look great but it looks better in-game, trust me.

This fix is also available as a mod on GameBanana![gamebanana.com]
