Okay, I do understand that you likely will not see the humor in it. For anyone else who may read this thread... consider a chuckle in that a gun store has an item offered and they are willing to take a -small- percentage of the actual selling price of it... and
hold that item for weeks (months?) and not actually sell it to anyone else until the buyer can actually forward full payment.
And then weeks (or months?) later, the buyer gets miffed if instead of same day, it takes an extra 2-5 days.
It doesn't have to be funny to anyone or everyone. I definitely find it funny.
