Absolutely agreed that - Tip is a thing which comes voluntarily not a forced one. So, DO NOT TIP them at all. I have said this before and I am now saying it again. "I want the government to pay them handsomely so that they don't indulge in this kind of extortion of money(believe me they literally abusing persons giving them money below their claim)" - GOVT? They are perhaps employees of a contractor and not GOVT directly.
"but I'm little pissed off by paying dynamic pricing and servicee charge tips to the government" - fight with case with the GOVT / RLY authorities not the waiters.
"In...
more... my compartment 85% of the people around me were reluctant to pay those tips as they were also behind the same judgement". - So, DO NOT PAY TIPS at all. It is not compulsory, is it?. NO. Not at all. If you wish to pay, pay handsomely, else DO NOT PAY at all. Its simple.
