I remember living in Germany before and finding the banks often in odd remote locations. Partly because we were with the military meaning there are plenty of soldiers in remote places needing access to money as well as having a good tax free income offshore. But also the farming communities still needed servicing for bank access. Odd to think though that many banks go extreme on security when more often than not reducing funds available or putting in a public place may actually reduce the risk of robbery in the first place. I remember talking to a bank manager before regarding “front of house” the counters we see when we are withdrawing funds. The maximum he said he ever had on the front of house was £30,000 which isn’t a lot considering 10 years in prison if caught in the UK robbing a bank.
At the same time modern banking today has tried to remove cash from the system where possible meaning most people don’t need large cash amounts and more likely just after money for a night out on a Friday and ordering a curry. Which makes these smaller shipping container banks ideal for many locations especially with banks being keen to squeeze as much profit out of us while downsizing branches all over the place.
