In US, even if we went to a restaurant with Buffet, for more than 6 people a gratuity (Tip in other words) of 15% of the bill amount. And they served only the Rotis and one Tandoori chicken at the table. Plates, Cutlery, Food you should bring out from the Buffet Table.
Back in India, even for A la carte, where you get separate set of plates and cutlery for starters, main course and dessert set and cleared , food served in plates, continuous supply of water, clean up of table after every course, Finger bowls, mostly everything at your service .. what do we pay in addition to the bill as a tip ?
I have seen more than one occasions where the tip paid was less than 1% of the bill. In actuality, the wages of an American Waiter and that for an Indian one would differ radically..
When I added a tip of nearly 8% ( an amount to round it off to nearest 100) , I got surprised eyes and opened door as I left .. :)
I only had to keep the payment away from the eyes of my Mom .. but thats fine.. I can explain her ..
