They always wait until after everything has been rang up... Then the dementia kicks in and they fumble around their fucking purse looking for the checkbook... Like it just now dawned on them that they have to pay for this shit... Where's my scrapbook of coupons? Oh I don't have a pen!
This is why you're in a fucking retirement home grandma! Die!
Do they call you downpunxx because you go down on every swinging dick within half a mile?
