I went into the Nelson NL on the weekend to buy a 1TB USB drive. I needed a hard drive that day and knew exactly what model I wanted. Hard drives are stored in a locked cabinet. I needed 30 seconds of someone's time to open the cabinet and accompany me to the checkout.
After 10 minutes, including unsuccessfully requesting the assistance of half a dozen staff members (including two having conversation behind the checkout) I gave up.
I went to Harvey Norman where I got a better deal in less than 1 minute.
