That's fine - you won't be the person that gets in front of me then. It's the people who get in the line, spend 2 minutes getting out their discount card to scan, then start scanning each item, unfortunately scanning an item involves...
- picking it out of the cart
- rotating it to find the bar code
- re-rotating it so that the barcode is facing down
- waving it in the general direction of the scanner
- realizing that they are too far away from the scanner
- refinding the bar code again (I assume this is in case it moved while they were scanning it the first time)
- waving it in front of the scanner again until it beeps
- holding the item in their hand while they watch the screen to make sure that the item was correctly scanned
- finally, placing the item on the belt
Repeat the above for each item ....
For even more fuin watch them when they have a produce item where they have to enter the product code.
Then there is whole coupon scanning, self bagging, and paying (god forbid they have cash).
