The level of sophistication of parking lots vary wildly across the globe.
For instance, in Singapore, all the cars are equipped with a chip that is hooked up to a special card. Every time you roll into a parking lot, or pass through a toll gate, it automatically deducts the money from your card. It's kind of like a pay-as-you-go SIM card for your phone, but for your car instead. Result: no traffic congestion.
In South Africa, some government Jeenius hatched a brilliant scheme to create more jobs: knock down all the parking meters and replace them with live human beings to collect the cash. This is one of those criminally-stupid ideas that could have been invented by no one who isn't in an official government position.
On one particular parking lot in London, England, a similar scenario took place. A lone parking lot attendant -- let's call him John -- stood there at the entrance of the parking lot, collecting people's money... every day for 30 years.
Yup, one of those old school working types. Don't see a lot of them these days. They just get a job and stick to it.
