Passing banknotes and coins from hand to hand will soon be an archaic notion, according to the proponents of a cashless society. Perhaps in attitude, if not in actuality, we are almost already there if the actions of bus drivers are any guide.
In Tauranga, one of their number caused a furore by refusing to let a boy on board because he had only a $20 note for his $1.80 fare. Any thought that this was a one-off incident was swiftly banished by revelations of similar experiences in Auckland. Drivers had apparently taken it upon themselves to decide the offer of legal tender was not, in itself, enough to gain access to their bus.
In the first instance, this refusal is a wretched advertisement for public transport. Those at Auckland Transport tasked with getting people out of cars and on to buses and trains must have been mortified that customers had been turned away on this pretext. Like the rejected passengers, they might well have viewed the drivers' actions as incomprehensible. Indeed, they are understandable only through reference to the deep penetration into society of electronic transactions, as evidenced in credit and debit card use and online shopping. Bus drivers who have embraced this process probably regard catering for a $20 note a dire inconvenience.
It is no such thing, of course. A decade or two ago, it would have been no more than a minor irritant. The same applies now, and people offering cash have every right to expect change or, failing that, a free ride.
