Unbelievably spiteful behavior, just as you'd expect from the sort of company whose employees leave $0 tips on $170 sandwich orders.

Shout out to the good people of Glass, Lewis & Co. for placing a $170 order and not leaving a tip. @glasslewis — Brendan O'Connor (@OConnorB_) July 22, 2013

Two days later, I got a text from the owner asking if I was free to talk on the phone at some point. We spoke later that afternoon. He told me that he'd gotten a call from the company, Glass, Lewis & Co. The company provides shareholder advisory services. Apparently, those employees were mortified that their lunch truck had tip-shamed them—the home office in San Francisco even got involved.

And it was unfortunate but he was going to have to let me go. The company has a way of doing things and he thought I'd understood that. I had embarrassed him and the company and that was that.

The food truck apologized to the customers on Twitter, and Glass, Lewis accepted that apology.
