I went to Atrium Senen in Jakarta. This Mall is famous with its car accessories. Also, there are several car repair shops in this shopping centre. We must park our car on the top parking level of Atrium Senen if we want to have reparation or accessories installation. I installed some car accessories. Everything goes perfect at the beginning until I finished the transaction and leave. However, I can hear click, click, click from my tire just after I went down two level in the carpark. When I checked my tire, I found one bolt as big as my finger on my car tire. What a day. Also, It was a little raining outside. Then, I went back to the top level. I asked the same person who installed the accessories on my car to help me replace the tire with spare tire. Also, I asked them why there was a bolt on my tire. Off course the answer is they don’t know. 🙂 Finally, all done. Extra coffee and extra tips make them happy. Extra bolt is applied to me. Buy accessories in Atrium Senen, you will get one free bolt. Quite promising.
