@walmart tax cut? buy a better checkout system like @sproutsfm

2017: mis.aq/walmart/@walmart tax cut? buy a better checkout system:
. I frequent the Walmart located at
Kolb & Speedway, Tucson, AZ;
in 2017 I started storing a lot of canned food;
often I would bring 12 or more of the same item;
double charged by cashier?
I'll try my luck at self-checkout;
I double charged me too?!
. the display has only 10 lines
and displays each item on a new line,
instead of using just one line
to show you how many times
you entered the same type of item;
so, it's not obvious from looking at the display
whether or not an item scanned
when you have more than 10 of the same item type.
. it would be easier if the new system would tell you
how many times you entered that item
rather than listing each entry separately
(like occurs when using the cashier
and their one-line display
tells you what just got scanned).
. doing that would also save a lot on receipt paper:
instead of 12 lines of canned greens,
there would be one line saying:
12 x canned greens.
-- @sproutsfm has a system like that,
and it is very easy to check for charging errors;
whereas, on the Walmart receipt,
it lists each item on a separate line,
making the receipt difficult to check
for cashier or machine errors.
