Yes, . . . malibber
is confused.
First off, DonDiego did not state that he pays for all his food before he eats it. malibber jest made that up.
Second, the question at issue is: "Do you eat before paying at the
supermarket ?".
DonDiego assumed this meant in them there fancy food stores where they let him push a cart, . . . they calls 'em "buggies" up here in the hills, . . . and select the comestibles of his choice off'n a bunch of shelves to take on home with him. Imagine DonDiego's surprise upon learnin' 'bout this here Publix-place where they weighs the grapes before they puts 'em on the shelf. Up here in Appalachia the grapes are loosely packed in some sorta plastic-baggy sorta thing with holes all over it sorta defeatin' the whole purpose of a bag 'cause things can get in and grapes can get out if'n one ain't mighty careful handlin' it. And then the check-out person has gotta weigh the grapes at the check-out stand and DonDiego's gotta be mighty careful that she or he, as the case may be, don't have her or his thumb on the scale with the intent of influencin' the indicated weight in a manner detrimental to poor old DonDiego's pocketbook. Well, maybe weighin' 'em before puttin' 'em on the shelf
is a good idea, . . . but DonDiego wagers that there Publix-place ain't got nobody out back in the alley sellin' fresh-made corn-likker outta the back of a pick-up truck like here. But DonDiego digresses.
As he was sayin', a "supermarket" ain't one of them there food emporia where wait-persons bring him prepared food to a table so's he can ingest it right then and there. For some reason them folks let him eat the food before paying; it's like a tradition or something. Anyway, 'cause of their thoughtfulness in defering payment until the meal has been fully consumed, sometimes DonDiego even rounds up the bill to the next even-dollar and suggests the person at the cash register give it to the wait-persons.
There's not much that can impress teechur more than a night out at " Hick's Diner, Bait Shop, and Taxidermy".
