Ghoulishly Good Business Sense

Prompt from DailyPrompt.com

“Goooodbyyyye!” Lady Xenia trilled as the last guest vanished into the waiting carriage. “Have a lovely day!!”
The carriage driver waved acknowledgement and clicked to the horses, who took off with what, had the humans been paying more attention, they might have considered unusual eagerness to leave the warm and safe inn and continue the arduous journey through the pass.
It was so very hard to weave Guises which fooled animals. Thankfully it was rarely necessary; few people travelling this road brought pets, fewer still paid heed to their mounts unease about their hosts. After all, the inn was of perfect repute.
Despite some guests’ (likely unintentional) attempts to test the staff’s patience and self-control.
Only once the hoofbeats had faded completely did she nod to the others, who as one sighed with relief and threw off their human forms.
“Can’t believe it!” Jason grumbled, his tusks curling in indignation. “Ran us ragged for three days, then didn’t even tip!”
Others snarled agreement, Xenia amongst them.
“Look, you know I’m on board with this charade normally, but-”
“We’ve been through this, Jason!” Xenia fought to keep her claws from unsheathing. There was no call for getting rough. That was just her annoyance - and riled instincts - trying to assert control. “Even if we ‘just’ eat the skinflints, word will get out.”
“Psh. People go missing on this road all the-”
Lais scoffed “Yeah, they used to, until we stopped eating them.”
“Exactly!” Xenia bestowed an approving smile. “Which is why we used to get a handful of travellers to lure in a year - if we were lucky.”
“They were always wan and desperate, too.” Homer’s lip curled with such disdain his fangs were left on full display. “Flesh sour and stringy. And never enough of it.”
“Yes, yes, I’m not disputing any of that.” Jason grumbled. “I just, it gets my ichor up, being treated so badly by food. I’m sure my ghoulish forebears must be snickering at me.”
Xenia patted his shoulder. “Only if they were smart enough to be rolling in succulent meat. I know pig flesh doesn’t go down with the same deep savour as human, but-”
“So much easier to get.” Jason finished with a sigh. “And it is nice, eating as much as I want. I just… humph! Not even a tuppence extra, after all the fuss they demanded.”
“Mm.” Xenia sighed. “Hopefully they’ll at least tell their friends about us.”
“I’d rather they didn’t. I doubt their friends - if they have any! - are less unpleasant and stingy than them.”
Ah. Hm. Good point.
Xenia looked around at the sour faces and decided it was time to lighten the mood. “Well, even without tips, this's enough money for a whole herd of pigs! What say we have a good old-fashioned murder party in the basement?”
Naturally that cheered everyone up, blood-curdling whoops splitting the air as fangs and claws were eagerly displayed.
Xenia chuckled. “Alright, someone get a Guise on and help me with the cart.”

Prompt was “Write a story which begins with a character stepping into a carriage.”
