@kus-knee,
You are absolutely correct my dear friend! I have this personal experience too. Not only those places in my country when I am going to a film hall this same incident will happen! Yeah this is truly a way of scam people! We have no other option to buy, so they over charge us! This is a perfect scam according to my language!
Really appreciate you effort and thank you very much for sharing such very useful experiences with us!
Cheers~
Thanks so much for your great comment!
