Why is she openly laughing at their performance?

She's rude.

Exactly. They rehearsed and practiced this and was proud that they got the chance and the woman laughs at them. So incredibly rude and inconsiderate.

She is one crass piece of work. He isn’t any better. Shame on them both. I bet she despises (him too) that the majority on this planet now mock the pair of them …. Scumbags.

Because she’s a crass moron.

Because she has no manners and is too stupid to understand that you should respect customs however silly they may seem. But haznoballs is actually no better, and he should know better.

Because she is rude and arrogant, she does not have the talent these people have

She is very common , and does not know how to conduct herself with any elegance or even basic etiquette.

She hasn’t got any breeding to be a royal she’s rude openly laughing at them. That’s not what our royal family do.

Shocking display of poor manners, lack of respect & unkindness from both of them. They're no great talents themselves to be making fun of others. Reminds me of her mocking the autistic singer in Canada

They are both laughing - totally unfit to represent the U.K. M&H = diplomatic nightmare
