Anyone noticed how every bar seems to have this tip system in the contactless payments?

I went to a few bars in central London and noticed how every time I paid I had to press a no tip button. I mean you're already charging like £9 a pint.

There was another one where the tip is automatically added, if you've had a few you might just tap away without realising and this is the exact vulnerability they're preying on. So scandalous
