@deprecated_ii You can still do this in some areas. Whether or not you can choose the "pay inside" option without having to prepay inside gives you great insight with the overall level of criminality in your area.
The scale goes from you can select "pay inside" without it being prepaid to having plexiglass and other barriers separating you from the cashier. You don't need much critical thought to figure out that barriers means you are in a crime-ridden shithole.
