The weirdest part about it was that refrigeration wasn't common in that area of Turkey at the time. But they had some kind of system for delivering colas (both bottles and cans) to vendors in small coolers with ice and the deliveries happened often enough the stall owner would just ask you to wait a couple of minutes if they had run out, because they couldn't talk business until both of you had a cola in your hands.

I remember one very prosperous rug store owner in particular, who was quite proud of the fact he had his own refrigerator for colas and ran a second business supplying cold drinks to neighboring stores.
