A few days ago during an English class, I moderated a student who recalled a recent visit to the US. He was stunned at the fact that the sales assistants not only greeted him upon entering a store, but would also bid him adieu upon leaving. This was received in awe by the rest of the classmates, as one inquired, “Even AFTER the mutual interest was over?” A skeptical other added, “How about if you hadn't made a purchase?” “Even then!” the former student quickly replied.
