Can one assume that was a true headline? That is absolutely terrible.
Unfortunately, many tellers have tubes and the canisters await the next customer. Shutting them down between customers may not be an option. Though they shouldn't be as hazardous either. But I agree, simply not serving the customers needs will dissuade them. "I'll help you this one time sir, please don't do this again" is not necessarily good for the bank.
