It's sad that you can't get that I'm not trying to minimize this but only want to remind this kind of **** happens everywhere. Here it's probably emphasized because she's a westerner and the security guy is a local. The fact is that such abuses with western security/police/customs towards foreigners also happens... I remember a couple of stories with poor fellas "accidentally" shot by police or badly humiliated. This kind of stupid behavior is not uncommon when giving some kind of authority to frustrated retards.
Totally different matter: you still have dozens of guys in Guantanamo who have been jailed for years sometimes without charges and decent treatment...
Of course nationals may have more influence than westerners and such abuses can arise anytime... as some Arab travelers wouldn't be surprised to be badly treated by some western immigration officers... A local security guy is abusing, this happens everywhere, it's just another day in the life
UAE is not Disneyland, it's still surounded by Iran and Saudi Arabia...
