How are people paying for coffee (or anything else for that matters) in Venezuela? I doubt many people carry bagd full of cash, especially if, as written in TFA, bank withdrawals are very limited.
Probably the same thing that happens anywhere that currency is unavailable or useless:
- informal systems of credit
- barter
- alternative forms of unofficial currency (e.g. Using food stamps or the equivalent for currency; using something like poker chips for currency)
- using foreign currency
This does put a damper on commerce, but prevents essential small-scale day to day transactions from grinding to a complete halt.
