whatever left .. like yesterday i gave barber 20. .and the bill was 12... so i leave it..
same goes for cab ride... but if i pay by card.. then i will make sure.. 5-7$.. i think one should tip always !
but why does a cabbie get a tip?
never understood the "silent" tip rule... because some professions get tip while others don't - like the bus driver.
What's up with that?
