Is Flex Right?

This is Raj. He runs a successful café on the ground floor of a large business park in Perth. It’s a place where many of his customers conduct their meetings over breakfast or a coffee. Others grab take away. Raj’s main concern is the bottleneck that occurs at the point of sale. His customers are time poor and he agonises over their frustration when waiting. A second payment facility is an option, but he just can’t justify the monthly cost. His peak period is short, between 9.00 - 10.30am and he rarely accepts payments over $99.99.
