Appropriate tip on a flat-rate cab? NYC

[Earth_First]

What would be an appropriate tip on a $45 cab from JFK to the Manhattan Cruise Terminal?

Thanks!

1. 15% (around $7). The nyc.gov page says JFK to Manhattan is $52.50...

Flat Fare from John F. Kennedy (JFK) Airport:
For trips between (to and from) Manhattan and JFK International Airport, the flat fare is $52.00 plus any tolls using Rate Code 2 on the meter. A NY State Tax Surcharge of $.50 will be added to each trip.

Thank you for pointing that out.

Not that it's any sort of dealbreaker...
