I was working a busy Friday night server shift at an AZ Mexican restaurant when I stepped into the kitchen to explain a special order to the chef. Something to do with allergies I recall. I did so in Spanish as it was the chef's main tongue when one of the manager's yells at me to "speak English". I'd typically brush it off but I was still miffed from a previous statement he'd made so I ask him why. He tells me that it bother's the customer's, of which I agreed but expressed that we were in the kitchen where there are no customer's to be bothered and that it was easier to explain a potential medical issue to someone in a manner they can clearly understand. He went off on the most cliche rant about speaking English in America, concluding with "as long as you work for me you will speak English." To which half the kitchen staff, a witnessing bartender, another server, and I walked out on. We walked to the restaurant across the street where the kitchen staff had a second job and witness the Friday night implosion of our previous employer over drinks. My only regret was the hell we left our remaining coworkers in that night.
