Held Prisoner in Hampton Roads

Riddle me this . . .

Yesterday, I bought three bottles of Sprite Zero to stock our little hotel refrigerator (more on that later).

Of course, nothing is "rung up" any more - it's all scanned.

So, the cashier scans the first bottle, puts it in the bag. Then scans the second identical bottle, puts it in the bag. Then scans the third IDENTICAL bottle and puts it in the bag.

Today, I watched a lady buy seven IDENTICAL candy baskets. The cashier scans the first basket, puts it in the bag. Then scans the second IDENTICAL basket, but the scanner won't read it. So, she tries time after time after time. Finally, the scanner reads it. Then she scans the third basket, but the scanner won't read it. So, she tries time after time after time. Finally, the scanner reads it.

Do you see my question coming?

Why not scan one item seven times and dump them all in the basket?

Especially if half of them take three or four tries.
