Before the DP World Tour Championship, Stenson upped the ante by giving Poulter 10-1 odds.
Poulter then said the loser would have to play waiter to the winner for a night out.
"I like to make these silly things, and he said he'd like to take the bet on," said Poulter. "I also said that if I do manage to pass you, we will have a nice night out, and he will have to pour my drinks for the evening. I think $1,000 isn't an issue to him but pouring my drinks all night might be a big problem."
Stenson, who's been nursing an injured right wrist, agreed to the wager.
"If he catches me, I can only pour them with my left, so he's going to have to hold the glass himself,” Stenson said.
Of course Stenson won by seven strokes on Sunday -- on a day when Poulter literally waved a white towel on the 18th green as Stenson finished -- so the $100 and night of Poulter in a waiter's suit is all his.
Poulter said Stenson earned it.
"I would expect him to be rather relieved to be honest with you, because I've thrown a lot at him in the last four weeks, I've given him so much stick and so have you guys, which is brilliant. So I'm sure he's a relieved man. He's had an incredible back end of the year, and you know, best player on the planet right now."
Stenson fired back that he hasn't forgotten about the bet.
"Yeah, I've still to collect that hundred dollar bill, ain't I. I'm going to get a photographer with me when we do that. Yeah, I'm not going to be serving him drinks. He can feel free to serve me one."
Pretty great stuff from two awesome competitors.
