I went to order food from the to-go restaurant, and they told me it would be ready in 10 -15 minutes. I said alright. But I didn’t have my phone with me. I don’t wear a watch too. So I went outside the restaurant and sat down and watched people. I can easily ask people, “what time is it?”
But I thought it sounded weird these days; who doesn’t have a smartphone? -even a homeless dude has it. So anyway, I had to figure out how to count 10 minutes by myself.
Started walking around the restaurant, and I saw other people ordering food from other places. I tried to understand how long it takes for each order and multiple with the people standing in lines and getting the total minutes, but it was not easy to predict that. Then, I started to check traffic lights. And I began to count by my head how long it takes the green light to turn red and red to turn green. Each one approximately took 41 seconds. Voila, I need to wait for 7.5 full cycles of traffic lights to go back to the restaurant to pick up my order.
