Seems they are developing self-service beer for busy bars:
Contactless beer
I’m slightly surprised at this, while in concept its not a bad idea, where does it leave bar owners re. duty of care?
When I used to work in a busy bar was drummed into us we, as bar staff, were persoanlyl liable if we served under-age or over-intoxicated customers. If that pump is unsupervised, and the point is it’s for very crowded times of year, seems both issues could become problematic.
I’d still happily use one rather than stand three deep at a bar getting too close to strangers armpits though
