I met a co-worker at a coffee shop this morning. I ordered tea for 10 NIS. I happen to like reusing my teabag for a second cup, so I asked for more hot water. I figured the 10 NIS was for the tea bag and the time. There are still some restaurants where you get an entire pot when you order tea, not just a glass.
The guy behind the counter decided that a cup of hot water would be the full price of 10 NIS, even without taking another tea bag. I decided not to order lunch at his coffee shop.
