I had the misfortune to have a Swiss Chalet lunch near an argument. It was actually more of a harangue since it was very one-sided, and I was on the verge of getting up to tell the antagonist to shut up.
I don’t know the relationship, but it was an older guy and a younger woman, possibly his daughter. He was going on and on about how she was cutting work to go to the gym, how she was being paid for working 37.5 hours a week but was only working 35, did she feel good about stealing from the company, it didn’t matter if she got the work dones, she was paid to be there, her a manager too, etc, etc.
What was particularly pathetic was that he only ever gave her a couple of seconds to answer before launching another tirade. I think she maybe said about 10 words in a fifteen minute period.
I suspect he thought he was making a good point, but he was just coming across as a complete dork. And he was putting me off my food, too.
