Kebab shop UX

The owner of the shop is very friendly. He speaks a dozen of languages but always greets me in English as soon as I walk in (he already knows that I don’t speak either French or German — both used in Luxembourg). He offered to shake my hand as he always does and asked how I was doing. I replied with my usual: “I’m OK”, and smiled. At this moment he noticed my book. He must have read the title because he asked me what is it that I do.
