If these people really were the dealers, they would know right away what they were seeing: a vampire ready to make a certain purchase. Sure enough, the bartender barely needed a word from Victor before he asked:
"Would you like to try a special drink today?"
"I only drink one thing, and it is red and it takes some hunting to find. I'm sure this place has none."
"You may be surprised. Come with me."
Victor followed the man to a back room, and saw multiple blood bags in the room.
"So you do have some."
"Yes. Care to sample?"
