I went to Decathlon to test a bicycle with my uncle. I was "test", not "buy". Because I had ordered a new bicycle from Decathlon on early Jul. It was xs size, road bike with straight hand rack. The price was fair, not so expensive. But the delivery time about one month as well as I only see the bicycle on the web. And Decathlon had demo bicycle for customer to test. So I and uncle had gone to have a testing with my favourite bicycle.

The journey was quite long. The bus had to pass two tunnels. When we arrived, the place like a super workplace, so big it was. Then I tested the demo bicycle which I saw on the web before. As staff member mentioned he placed the order for me but there was no feedback temporarily. I thought the time had passed about half month, would the order be successfully? I didn't think so. The appearance of existing one (only one) looked good! Thus, I bought it.

We went to downstairs by cargo lift. Then my uncle began to phone the van but not successful. I tried to call the van and it could be done finally. Until I saw my mobile which had a missed call. Yes, it was the driver. I said to myself and I returned his call. The driver asked about our direction and my uncle told him then hanged off the phone. Later, the driver phoned me again and said once again: could you go to the bus stop where I will pick you there. I said: If I know the way to the bus stop, I definitely go to the place early, but I didn't know the way to go. The driver then said: you wait a while, I turned my car to your side. When he got out from his van to pick us, he said to us with a bitter smile, he pointed his right hand side: this is loading bay, on his left hand side: this is the bus-stop.

I thought he was unfortunately to meet me as I was blind on the direction on the street.
