>>508163323 (OP)I agree and disagree.
As a Customer and Former NEET: I loved it. I could shop and browse at my own convienance. No one around. It also helped me as I was usually up at night anyway, and made me feel "more normal".
As an Employee Who Has Done Night Shifts in a Box Store: It's a terrible idea. 80% of the customers are junkies, criminals, or maladjusted social outcasts. Sales were low, and this was the most frequent time thefts happened.
The only way I could see it working if trusted customers bought some sort of "night pass" and had to scan it to get in and shop. It would filter the criminals and junkies out if you made it like $100, and made it so they could easily get arrested by tying IDs to entry times.
