I think a couple of those "stashes of twenties" are pretty awesome. and maybe drop one of them gold bars at the front door would be a cool conversation piece.
"yes ma'am, you heard me right...it is 45 cents a sqft. Afterall someone has to pay for the gold bars holding your door open." Just smile (preferably with your gold tooth flashing) and grab more hoses or whatever..
Those are awesome! Actually if they were relatively inexpensive it'd be fun to get your company name and phone number on them and give them out to new customers!
