The moment I saw the picture I remembered that piece of news.
So, one more limit passed.
But, I wonder how the experience is going to change....
For customers, it's simple, tip with a fingertip , but the stripper has to wait 30 minutes for confirmation...
They could install some panels in the club monitoring the addresses so the stripper can see when she gets a tip without checking her smartphone, otherwise it will not be the same as throwing bills around.
Ohmibod linked to address?
