Awful or Daring....?
Law does not say not to charge but it also does not say to charge. Tip is optional but making it a part of bill is compulsion.
The price of each item includes service cost also along with raw material and making charges. Why service charge separately other than service tax.
It is encouraging undue extra income. Many are in the habit of giving tips even for free service. They pay at air filling at petrol pumps,gas cylinder delivery and post man/ courier boys etc. They are paid for that service, why extra. are we not encouraging them to expect free additional income which is unaccounted.
Some may argue that these are small amounts. But small or big, undue is undue only. more
