Sorry, I did not make it to Bengaluru. I had an appointment with my girlfriend in Mumbai, but she was repelled at the border and sent back to London. Her visa (multiple entry) had required her to stay away from India for at least two month after her first visit, and it were only 5 weeks. She didn't know the regulation, and the airline didn't check her passport carefully on check in. So -- she was trapped at Mumbai airport, deprived from drinking water, no telephone, and had to go back London. A really bad experience.
The German embassy said, that this regularly happens. So why the Indian government invents such special regulations? Do they want to trap foreigners on Indian airports? I hope, the regulations will soon be reworked. At least, the immigration officers could be so friendly to offer water and phone calls.
So, we had to change our plans and spent three weeks in Sri Lanka. Did not need any visa to enter there. It ment about 1000EUR additional flight costs for us, but we had a good time on the island :-)
I mean, we could have had a good time in India, too, but if India doesn't want us...
