In a basic sort of way, yes. It's figure total, apply tax, then round. Which, for a race of intuitive mathematicians would be infinitely easier than keeping track of 16 different coins.
I mean the change sections of a cash drawer for a Point-of-Sales system would be a
nightmare for those people.

For intuitive mathematicians that's like telling you to keep track of your debit card. Sure, some people have a horrible problem with that. But, the majority can pull it off.
And, most stores have scales so, they can fill up a bag with potatoes and know how much it weighs so they can adjust the running total in their heads.
