How much money should I give as a tip to a hotel boy in Mumbai / India, for carrying my luggage or to reception girl or restaurant waiter, for being generally nice and helpful? What amount is best to not offend recipient (with to low amount) and in the same time to not make him uncomfortable (with to high amount)?
I started tipping them with 100 INR per each tip. My friend said, that he is giving 50 INR. However, after comparing this to local market prices (20 INR per short rickshaw ride or 150+ INR for burger at Burger King), I feel like 50 INR is way too low amount.
Please note, that answers like "Nothing, this is part of their job and salary" are not interesting for me and please do not put answers like that.
Is there any "uncomfortable" amount at all? Can I give 1000 INR extra for the whole stay (week), if I feel really generous or would that be received like something wrong?
