Hmmmm we all know what happened to Dr Dao... not saying this is not the best approach, but is it really fair on the pax? What if the pax feels threatened by the staff? Are the customer service staff not meant to “serve” the customers or have i gotten this the wrong way round?Sometimes its very best not to talk back to staff at an airport no matter what.
No matter how rude the staff are, (airline or security or who ever).
You certainly don't need to be taken by away by airport police for being seen as a threat.
Even if you thought you were right but staff might feel threatened.
I certainly wouldn't do it at an airport of all places.
