Although many pensioners are unable to afford taxis, there may be occasions when urgency or convenience outweigh the expense.  However if you are unfamiliar with taxis and their drivers, it’s safer never to use a cab

fitted with a sat nav, as that probably means the driver is Lithuanian and has very       little knowledge of the local area

bearing a Hackney Carriage Licence plate, as these are normally fitted with an automatic homing device and you will end up in Hackney

whose driver is playing on a games console or heating lasagne in a microwave

in which the back seat has been removed and replaced with straw bales

which has a wood burning stove in the front passenger well

which is black

or yellow.
