Napkins. WTF!

How come when I’m in the Chevy and creep off the boulevard to grab a burger at the drive-thru, the guy working the fries completes my order by loading seventeen napkins into my bag? Am I supposed to leave a trail of napkins on the road as I leave so that I can find the restaurant next time I’m hungry? Should I upholster the interior with these napkins? Does this dude think I’m an uncoordinated slob? F-U!! *double birds*
