To think my cousin has let the family down (very light hearted)

[NotAnotherScarf]

My little cousin (49) has messaged me to say she is in the local Wetherspoons and has deliberately sat at the regulars table. She has made her husband and her sister and her husband sit there too.

Some of the regulars have now come in and are not happy.

AIBU to think she's let herself down, let her country down and more importantly, let her family down.

I am so disappointed in her.

She’s only a little cousin, I’d support her and cheer her on.

I'm not sure what aspect - the fact she's not a regular and you want her to be and she hasn't earned her stripes, or that she's spotted a cheap pint, or that she values a quiet eating and drinking environment where people aren't allowed to use speakerphones.
