They don’t allow alcohol at self checkout so I barely get to use them. Maybe I should just pay for my food and steal the beer.
Ours allow the sale of alcohol but an employee must verify age.
My Costco does it by having an employee ring up alcohol. My Walmart sends an associate to punch in an age and my grocery store does it remotely. The customer service person minding the self checkout just punches in an age on their connected phone and off you go...pretty much no waiting.
