I was a regular customer at the La Salsa restaurant in Mira Mesa. I knew the staff. One day they starting addressing me in Spanish. We had conducted business exclusively in English for almost 3 years. When they refused to speak English, I ordered my food in Welsh. They looked really perplexed. Their understanding of Welsh was less than my understanding of Spanish. I suggested we both function better in English. End of problem.
Hey, my wife is Welsh...Pembroke!
