Ghost Drinks

The bar serves ghost drinks.
What’s a ghost drink?
Take an ordinary drink, like a Jack and Coke, and then bubble the spiritual essence of someone that’s recently died through it.
The fresher, the better. Has a tangy, sparkly feel. Like a battery.
If you sip it, the ghost’s ectoplasmic residue will be all that you taste. And that slime is disgusting.
You have to drink it. Quickly.
How the bar gets the ghosts, that’s another matter entirely.
I could tell you the secret, but I’d have to kill you.
Seriously. The last guy I told is in your glass.
