It is OK for the Steve Buscemi dance twirl with the airline attendant, since they both just had sex in the lavatory.  Thin privilege = being able to fit 2 (or more) humans in a airplane lavatory for some sex.  So, that is how I saw that dance twirl, it was more of a thank you for the sex in the lavatory:) Note: fats hate lavatories and need to use full size bathrooms.
