Chartering a taxi to yourself, direct to your destination, rather than sharing it with other passengers along a fixed route.
“Dropping?” is the question a taxi driver asks, or the word you use to say what you want.
Ghanaian taxis have no meters. The fare for a dropping is whatever you agree before you get in, so ask a local what a given trip should cost before you need one.
The alternative is a shared taxi, which runs a fixed route like a trotro, picking up along the way at a fixed fare per passenger.
