It is so sad to hear such a story. At least if they don't want to let her in, they should not call her prostitute and they don't have the right to call anyone like that.

It is very simple like being invited to a place and you did not like that food there, you can't say:that food got a creepy taste or who cooked that so i can give him/her some lessons. All you have to do is thanking the people who invited you and tell them in a nice way if you can't eat that food or keep it for yourself depending on the situation.

I don't know from where do they got such strange ideas, how can they judge people like that? If I traveled to Romania or Thailand, would I be a Pi** [sorry for that] and get refused too?
