Limiting the power outlets used to be effective until laptops started getting USB Type C. Now everyone can just bring a power bank to charge their laptop, right? Charging for the Wi-Fi would probably have a greater effect, plus additional revenue stream, but then would this negatively impact the experience of other more casually sitting customers. I would be curious to see the coffee purchase numbers for a working squatter vs other customers. If someone sits in a coffee shop for 6 to 10 hours a day, I can't imagine them buying only one coffee. People can get thirsty throughout the day. And if they get hungry too, well, that's additional revenue if the working squatter doesn't want to lose their spot just because they went for lunch. Or maybe they're on a roll, and can't afford to risk breaking their zone by going to a restaurant. To determine whether the working squatter has a higher or lower sales per hour number would probably also depend on the cafe's sitting customer turnover per hour.
