"I was at a Craft Store in my town, and it wasn't too busy, but only one register was open. The cashier, a teenaged girl, I could tell was working as best as she could. The process was a tad slower however because she had a stutter and a bit of a lisp. As she worked through the line, asking the usual questions probably mandated by the big wigs (I've worked in retail, it's a thing), the man behind me began to huff and puff. He muttered something about having places to go, he was in a hurry, etc.
I ignored him until I heard him start to mock her to his kids, 'W-w-would you l-like y-y-y-y-y-y-your reSCHKeet?'
The kids began to laugh. It made my blood boil. Especially since I could tell the cashier heard his mockery. That really made my blood boil. When a person doesn't respect retail employees as people, it's the best way to tell whether a person is rude or not.
So, when it was my turn at the register, she asked me in a small voice 'Are you a member o-o-of the rew-w-rewards club?' And I looked smugly at the guy behind me, and back at her.
Me: 'The rewards club? Oooo that sounds great! Please explain it to me?'
She seemed surprised at first, but then looked at the guy behind me, and then it clicked. I have never given my information so slowly in my life. Never had I asked as many questions as I did. She smiled and answered my inquiries, while the guy behind me was seething.
Him: 'Can you hurry up, please?'
Me: 'And miss out on these great rewards? As if!'
I only held him up for about five minutes, but wow, it felt so good."
