This is the worst idea. So bad. This is amazon's AWS for drinking. This is so dumb so dumb. This just makes me imagine the person who thought up this restaurant conjuring ideas of how they can penny pinch all their customers.After my unfulfilling burger we went to a new bar that, through sheer luck, was also trying their hand at automation. The bar had a beer wall, 10 taps each controlled by a RFID bracelet you could rent at the bar. Your rental opens a tab and you're charged per fluid ounce, down to the 10th, of what you pour.
I had a friend who wanted to patent a system that basically enforced pours on bartenders through RFID and metering. I told him that this is exactly what is done at low-end establishments in Vegas where their turnover is measured in weeks and where their customer retention is zero.
