Bad airline and check-in agents in Lusaka

I flew Fastjet in 2015 and was much better airline. Recently, I flew Fastjet from Lusaka to Dar es Salaam on July 14, 2018 (Flight 205). Buying the ticket online was easy but the horror was at the Lusaka airport. The check-in agent of Fastjet was so rude and creating all sorts of problems. He asked me about my Yellow Fever card and spent 10 minutes examining it. He then asked me why my last vaccination date was 2006 (not his business). He then moved to my passport counting the blank pages and was going to prevent my check in because I had only 3 blank pages left. He did not ask me if I needed a visa for Tanzania or not ( I had one in the passport) but he was just giving me hard time. He then I needed to pay $32 for my luggage. That was not clear form the very fine print of of the ticket. If I did not had the cash, I would have gone outside the airport to pay by credit card and return back to the very long line before security at 1:00 a.m. All in all, very bade experience and I will never fly Fastjet again.
