Better, at least for me, to remember the "break points" in the ASCII table - 65=A, 97=a, etc...
You remember the decimal ASCII values? How useless! 0=0x30 A=0x41 a=0x61. I did not need knowing the 65 value for decades. Hexdumps are used quite more frequently than decimal dumps, in my experience...
Moreover, cashiers are used to do the change to round numbers.
If you had given them $20.00, they could probably have calculated that the result would be 73 cents. To do this, they use the method of nine's complement: remove 1 (cent) from the total, then the difference becomes obvious: 19.99 19.27 ----- 00.72 Then re-add the cent removed at the beginning -> 73 cents!
When giving the cashiers $20.02, it means that they cannot use the usual method so they prefer to rely on the calculator machine.

I guess it can be used to generate spam.

Wow, this is really bad formatted.
