Cool, I live in Hyderabad. Only about 5 miles away from Raheja Mindspace. I live on the road to the Seven Qutb Shahi Tombs and Golconda Fort and I recognize where most of these photos were taken.
A good tip is rs500. An acceptable tip is rs100-200. If you want to flaunt or impress then rs1000.
And as for meals, the avg tip is 10-20% or so though optional.
Yeah, this is bullshit. Indians don't tip. There is no tipping culture around here. Yeah, if a dude delivers a 500-liter refrigerator to you on the third floor of a building with no working elevator, then it's the polite thing to do. Otherwise, people don't generally expect tips. Unless you are a foreigner. Then, they know you come from a tipping place (that's a weird phrase) and expect one. I do tip because people in the service industry make shit wage and it's the nice thing to do.
As for why you see all the security and metal detectors, well, there are a lot of terror cells spread across the country and the government does not want to take any chances. I mean, by now you must have noticed the sheer number of multi-national corporations that employ thousands of people in Hyderabad - Amazon, Microsoft, Google, Facebook, GE, Monster, Electronic Arts, Wells Fargo, Bank of America, Qualcomm, Dell, HSBC, Bank of America, Deloitte, Du Pont, Cognizant, Accenture, Oracle etc. (literally dozens of similar more high-profile employers)....all within a 5-mile radius. And all of this came up in the past 12 years or so thanks to the Chandrababu Naidu government. They don't want a bomb going off scaring away foreign corporations.
Also, as a Hyderabadi, I can confirm that there are very few hot women out here.
