When I went to India with a friend a few years ago, we were at this small restaurant in New Delhi that I can't even recall its name now, we were just looking to get some snacks and take a break from all the walking we had done that day. We sat down, browsed the menu, waved at the the waiter to come over so we could order.

Me: Hi, do you have free Wifi here?
Waiter: Yes.
Me: What's the password?
Waiter: You need to buy a drink first.
Me: Sure, I'll have a coke.
Waiter: Is Pepsi ok?
Me: Yea, how much is it?
Waiter: $1, Miss.
Me: There you go. So, what's the Wifi password?
Waiter: You need to buy a drink first. All lower case, no spaces.

My friend and I bursted into laughter. It was the most refreshing Pepsi I've ever had.
