VISA bills

I watch people go to great lengths to make sure their VISA receipts total even numbers. They squeeze the gas pump 10x just to make sure it's a 'perfect' pump - $40.00 even. Then whenever they buy food, the total is $22.17 and they do the math to make a $2.83 tip so it totals an even number. On and on it goes.

Here's my question. When does a VISA bill ever come to an even number? And even if it did, who pays a VISA bill in person anymore? It's paid electronically and if you pay it through your bank electronically, who cares whether it is an even total?

So be a man. Do the right thing.
