Dominatrixes are using Wetherspoons' app to get free drinks from their clients - or "piggies" - during nights out.
Women are demanding men pick up the tab for pints and pitchers of cocktails - and their "subs" are happy to follow through on the orders.
The practice is so rife that there are a number of Twitter hashtags and accounts dedicated to it.
The Wetherspoons app allows anyone with an iPhone or Android device to order food and drinks to their table without getting up.

It can be used remotely, meaning that many are tweeting their location and table number while begging strangers to pay for their meals and drinks.
A subset of dominatrix users, who demand subservient men pick up the tab for their grub, has emerged.
Known as financial dominatrix - or findoms - they upload saucy pictures and video in return for getting their bills paid.
A user named Goddess Sinead tweeted: “Been away a while, what better way to welcome me back than subs sending my drinks! APPROACH #spoonssub #spoonsslave #wetherspoons #drinksslave #findom.”
Goddess Jessii wrote: “Rinsing you piggies for your cold, hard cash is thirsty work. Wetherspoons subs come out to play - cocktail pitchers to table 92, Twelve tellers Preston NOW.”
A user known as Prince$$ Becka uploaded a video of herself, demanding: “You heard me piggies, get my drinks in Wetherspoons.”
Another user, called Ruinatrix, uploaded a snap of herself in a Wetherspoons toilet, writing: “I’m at Wetherspoons and I want my #spoonsubs to BEG to sub my drinks.”
On another post she wrote: “Queen in spoons right now....
“Play. Spend. Serve. Worship.”
Goddess Dreamz has uploaded videos of herself in Spoons, alongside captions including: “Chop chop goddess is waiting!”
MistressAX posted a snap of herself begging for drinks, adding: “At Wetherspoons. Beg to send.”
A Twitter user named Princess Merci wrote: “I love spoons! Not because of the food tho, I love it cos weak beta males can order exactly what I want to my table! Serving me hand and foot thru your mobile!
“Download the Wetherspoons app now!”
And Mistress Blake added: “Someone send some halloumi fries or chicken bites xxx”
She wrote in another tweet: "Celebrating our 9th and 10th pitchers from you pathetic losers."
Another user, called Goddess Ana, demanded: "Table 49, Perkin Warbeck! Order us chips or cocktail pitchers!!!!"
She then posted video clips of pitchers, chips and halloumi fries.
An account called SpoonsPayPig retweets requests.
But some dominatrixes were left fuming when their “piggies” only sent an 85p ale or were late sending their orders.
Goddess Lia raged: “When I say send me a drink i don’t mean an 85-f***ing pence ale.”
Mistress Meg fumed: “Wetherspoons subs... drop to your knees and start sending I’m not gonna ask again.”
The Wetherspoons app was launched in March 2017 and earlier this year was recording a million transactions annually.
A Wetherspoons spokesman said he was aware of the trend but declined to comment.
