Solution: Request more bags!!!
Maybe it was the 5 hours Laura and I had just spent drinking wine, typing emails, researching what we wanted to do with the next few months of our trip and listening to the seductive sounds of Pure Moods, Vol. 1 at Pizza Libre or maybe we both just can't speak Spanish. All I know is that when we went to buy a bottle of water and two snacks our brains we not equipped to handle the remedial conversation that happened at the check out counter. Within seconds of the first word being uttered from the checker's mouth a thick cloud of confusion set in and Laura and I started spouting nonsense holding out our water bottle, snacks, money and apparently asking for more bags than was customary or necessary. We walked away from the stand wondering what the hell had gone so wrong in a situation that is usually guaranteed to be simple...Moral of the story: When nervous or in doubt, just ask for more bags.
