Lol!
OK, if observing that someone who is dressed sloppily, has an intensely bitchy look on their face, is obese and is dismissive when she responds to the friendly checker, is bad advertising for any organisation, makes me a judgmental asshole... I respond, "Guilty as charged!"
I'm not quite sure why that puts your knickers in such a twist... unless maybe my description landed a little too close to home for you.
Maybe she's a sweetie pie and just had a really bad migraine. Perhaps she was sore and uncomfortable from the good stiff rogering she had the night before. It doesn't matter. In my opinion she wasn't representing JW.ORG very well. If you disagree, that's OK with me too. Maybe that demeanor works well for you.
Anyway, keep on keepin' on!
