| Please improve staff training, the quality of service is a disgrace, embarrassing and ill-mannered. Poor communication with customers, no greeting with a smile in the shops, when asking for help people don't open the mouth to talk, they just point. I even asked a lady at the Duty free shop for arrivals, why everyone is not responding verbally and give proper directions or answer nicely to customers. The whole airport a majority of people are the same. Staff in Passport check section can't even smile or greet customers upon arrival. They just take the passport and stamp without even saying hello. I understand you serve hundreds of customers per day, but the protocol of such a job requires a special welcoming approach. Foreigners are bringing money to the country and boosting the economy no need to be cold to them. I even asked one of the Officers why they don't greet customers let alone smile. He said according to SA culture, the person coming into the country must be the one greeting. Come on!!! we are in a modern world with diverse people and this requires adaptability when dealing with people. It costs nothing to serve people with a warm and friendly approach, but its always worth it. Another worst and embarrassing part is greed. They ask for some money to buy a drink from customers. That's a shame!! Create a forum to report this in the airport immediately it happens. It's always nice to give money or a tip to someone as a token of appreciation but not when they literally ask for it. Please come and learn customer services at Heathrow London. This the best place to benchmark. Airport staff provide the highest standard of service i.e professional, friendly, knowledgeable, understanding of diverse cultures, mannerism. Absolute great service in London.
