For me, it’s a big no. I personally am self excluded via photo from all uk bookmakers and have gambling block setup via monzo.
The gambling industry isn’t a good one to start moving with banking I’d say ! If the house always wins as they say, you would soon risk your brand being associated with that impression by partnering with them.
Also, gambling operators use very prominent marketing and ‘clever’ ploys in stores and would use the opportunity of having you in store to offer free bets or introduce you to their other ‘services’.
That’s just my personal opinion though! There is just as many paypoint locations as bookies so it’s not needed add-on for me at least.
