HMMM never imagined that one...
ALWAYS ALWAYS ALWAYS ask for extra ketchup and NAPKINS at the drive through window as they hand you your bags to add extras in front if you.
Ask you how many you say as many as they can spare you are heavy ketchup and NAPKINS user. (Just short of them actually charging you extra for it)
They wipe pretty good first 2 dry crumpled then followed by real almost dripping wet (from the sink tap! Spit is too slippery!) then followed by 2 to 3 more dry ones. Stick one in the crack after that just in case.
