GPRS Activation on Airtel Mobile

I called Airtel Customer Service, 121, and asked the agent how can I get to surf the net on my mobile phone, and how to connect my laptop to my phone. He said that he could activate GPRS right away and that the best plan for me would be Rs 98 per month for 2Gb download and 0.30 paise for every additional 50Kb download, and that the service would be available on my phone within four hours. The monthly charge will be pro rated on per day basis, and the deactivation would be possible by calling the 121. For any help in connection with the laptop using cable or bluetooth, I could call 12118. The agent informed that I would be receiving SMS messages with the settings for my phone.
I asked him to activate the service. Soon after, I was able to surf the net. This was great !
Although I was able to start surfing the net from my mobile without waiting for these messages, still, the messages should have come say at the most within four hours. I got the messages late in the night at 3.35AM, and I saw them the next morning.
Had I waited for the messages, then, the service would have been usable only after at least (6:30 PM to 3:30AM) 9 hours ! That is too long a time.
In as much as I am delighted by almost instantaneous availability of the service, I am a bit unsure about whether the procedure at Airtel is actually good to make the service available so soon, or my phone per chance had settings enabling me to commence surfing right away. I guess it is the latter case.
I would like to hear your experiences with similar services.

Cappucino at Marriott Courtyard

I was with my friend at the Executive Lounge on level 15 at Marriott Courtyard. It was about 11AM on Wednesday 7th July 10. He ordered two cappuccinos to the lady in attendance. She went in, and then cam out and asked, as if unsure about what she had heard before, "Sir, did you order two cappuccinos ?". My friend answered in affirmative. About fifteen minutes later, a boy came with two cups of coffee, one had white froth on it, and the other had a dark brown thin froth on it. The boy placed the cups in front of us, the dark brown thin froth cup in front of me and the other in front of my friend. I commented to my friend, how come it was that the color of the two coffees was so different. He quipped, "they just love you more". I removed the thin froth in my cup only to find that the coffee was BLACK COFFEE, not the cappuccino my friend had ordered. I was so so so surprised and amused. One simple order, in a hopelessly up market hotel, could not be executed correctly, let alone with perfection.
