I think it’s just part of the mumsnet terror of normal eating habits. I’m still waiting for the poster who said nachos and hot dogs are grim and disgusting to come back and explain if she ever goes to any restaurants, cafes, places that sell street food. How on earth would you cope with life if triangle shaped crisps with some cheese sauce on them makes you want to projectile vomit all over screen 6 in the middle of a Matt Damon film.
Same with the HUGE buckets of popcorn and MASSIVE troughs of Coca Cola that people ‘guzzle’ and ‘slurp’ and ‘gorge’ on. In the real world we all just watch the film and maybe have a drink and popcorn or sweets.
