This service is called a 'nightly drop box' or sth, I suppose it's useful f.ex. for for grocery/liquor store owners, I believe a successful branch or two can easily make 6 figures income in a day. This one was actually 7 figures (1m EUR ~~4.5m PLN), around here gas station networks have private security companies to handle the pickups and drops, and I can easily assume a 1hr ride around a few branches (gas stations handle CCs, so there's probably less physical cash while the income is bigger than a liquor) will easily make a few mil, but I don't know if the sad guys drop it nightly in bunches or secure it on their own and transport it to a bank vip area during the day.
