The evening had started out a little quieter than usual but half an hour in and Charlie could tell it was going to be packed all night. He hadn't been scheduled for more than floating for the evening but he had soon stepped behind the bar, slipping easily enough into the role.
He was finishing up an order of cocktails complete with magical flames for a group of mostly witches who clearly weren't long out of Hogwarts when he saw the man come and sit not far from the bar, trying to catch the eye of the woman who was currently out collecting glasses. She walked over and pointed him towards the bar, obviously explaining they didn't do table service on regular nights. He took a stack of galleons and assorted smaller change from the girl who had had several of the group's money shoved into her hands. Counting quickly he nodded his thanks when she waved off the change. He dumped the stray sickles and knuts into the tip jar instead.
He moved off to the gap in the bar where the man had been directed and raised his eyebrows at him. "What can I get you?" he asked, not bothering to raise his voice too much. That was the usual first question when behind the bar.
