News has filtered up to Camp Teacup regarding a proposed chocolate currency standard. We approve, and will commence high-level training*.
Ten months of the year, no refrigeration is required in our northern climes, but those other two months dump all the heat at once. Also, society appears to be
collapsing a bit, hence the need for a practical (edible) currency AND the ability to protect it and oneself from premature separation by ballistic or stabby methods.
Citizens will require a coin purse** fashioned from Thinsulate insulation, Kevlar (bulletproof structural strength) and various customizable outer layers retained from bovine sources, or the brightly-coloured traditional Nauga-herds (waterproof, in case of sudden tornado, flood or similar).
Cheaper models will maintain the temperature of previously cooled chocolate coins. The upscale model contains miniaturized coolant lines, evaporator/condenser coils, compressor, and rechargeable battery.
* The only time the Sgt runs is when it's necessary to chase the rogue who stole the chocolate.
**Available in coin purse, wallet, conventional purse, book bag, backpack, secure briefcase, or large luggage (extra compartment for dead body), depending on the individual's net worth and professional need. Choose the size and wearable location based on protection requirements.
