How to use the S.A.M machine

I headed to my client's place after lunch. One of the beauticians there treated me with one of Auntie Anne's sour cream & onion pretzel. It's my first time eating pretzel and I am in LOVE with it! Its so delicioussss (not that I am hungry as I had quite a heavy lunch b4 that).
I visited Auntie Anne's site and realized that there're so many other flavors available and I'm going to try most of them soon. :p

I went to a S.A.M machine after work as I had to weigh a letter for postage. There was this lady who was using the machine, whom I wished I could have given her a lesson on how to use the machine effectively and efficiently. She had 3 different bills to pay and this was what she did:

- scanned barcode for the 1st bill
- enter NETS pin
- selected "no other transaction"
- took receipt
- scanned barcode for the 2nd bill
- enter NETS pin
- selected "no other transaction"
- took receipt
- scanned barcode for the 3rd bill
- entered NETS pin
- selected "no other transaction"
- took receipt
- ended her transactions finally!

If she did the following:
- scan barcode for the 1st bill
- select "another transaction"
- scan barcode for the 2nd bill
- select "another transaction"
- scan barcode for the 3rd bill
- Enter NETS pin
- Take receipt
- Leave the machine!

, I would have reached home earlier...
