Airport Craft Brewers O R Tambo International Airport

I was traveling to PE early on Friday 21 Feb. 2020 and I usually support the airport craft brewers where I can smoke and have a beer. Being that time of the day I preferred not to order anything from the staff member who wanted to serve me. He then promptly told me to leave the premises and I was not allowed to finish my smoke. It is not the fact that I had to order something so I may smoke there as I have done for the past eight years supporting them but the manner in which I was made to feel like a ******** in front of the other people in the bar. (some of which were also not having anything, ) This is the only smoking facilit at Or Tambo International Airport after passing through security and the Airport Craft Brewers know this and is exploiting it. I have not been insulted in this manner ever before and my friends, colleagues and family have taken note of this incident. The manager at the time was not very helpful at all. Is this the way they will treat international tourists also? Shame on you Airport Craft Brewers.
