Some stores in the UK don't have the modern tills that calculate the
change the way you describe. I have fun sometimes when the total is
2.83 by giving the operator 3.03 (and expecting a single .20 coin in
change). Some almost have a mental breakdown as they stare helplessly
at the odd sum of money I give them.
I sometimes make a profit on the deal if it is more complicated.
Recently the total came to 7.52 and I offered a 10 pound note plus a
.02p coin (expecting 2.50 in change). After a bit of hesitation, I was
delighted to receive 3.50 in change.
