the first half of the spam is to be hidden around the store randomly, to be found later.
the second half of the spam is to be distributed about the group, then taken to a specific register where the inguiry "how much is this?!" will be made, and, upon recieving the answer, placing the can down next to the register, exclaiming "too much!" in an annoyed tone, and storming off. repeat with remaining second half of spam, each person at a time.
