Can you wait five minutes outside?
'Fuori' — 'FWO-ri'. Two syllables; 'uo' is a diphthong pronounced in one beat.
Ask when you need to quickly pick something up from a building while the driver waits outside rather than driving around the block.
'Fuori' means outside. Combined with 'può aspettare' (can you wait), this requests the driver to park and wait. The meter continues running, which is the standard Italian arrangement for waiting.
Parcheggi qui un momento.
Park here for a moment.
More direct; 'parcheggi' is the formal imperative of 'parcheggiare'.
Sono veloce, massimo tre minuti.
I'll be quick, three minutes maximum.
Reassures the driver with a specific timeframe.
Mette le quattro frecce?
Can you put on the hazard lights?
Practical request for safety when stopped outside a building.
Double-parking ('doppia fila') is extremely common in Italian cities, especially in historic centres with no stopping space. Taxi drivers are very used to this and know where they can safely pause.
