Like tipping in general, this is largely a personal choice and depends on the service rendered. If you feel that the person has been helpful, then tip them. If not, do not feel obligated to tip. However, Panamanians don’t earn huge salaries, so these tips can be an important source of income. For porters or baggage handlers, $0.50 to $2 should do it. For more extensive services – such as for naturalist guides or shuttle drivers – you may want to tip more. Taxi drivers do not expect a tip.
