Instead of nearly running into trouble haggling, maybe Aubrey (or anyone else planning a stay in Cameroon) should use pay-as-you-go mobile airtime credits as legal tender.
Badala ya kuwa karibu kujikuta katika hali ngumu, labda Aubrey (au mtu mwingine yeyote anayepanga kubaki Kameruni) anapaswa kutumia vipaumbele vya matumizi ya fedha-yo-yongo vya anga za mkononi kama vinyume vya kisheria.
