I needed a tool from a DIY store. There was a hectic and irritable atmosphere throughout the store. The staff seemed overwhelmed by all the questions from the shoppers. There were no batteries left for two models I had chosen. So I went in search of a staff member for the third time. A little irritated, the staff member I found took my question and searched for information in his mobile. "There's no battery for this tool at the moment either!" I heard him say. And then he recommended a simple device "all inclusive" - with battery and charger. I gratefully accepted. Immediately, a new customer occupied him with questions. I told him, "Thank you very much for your competent way of helping me!" He turned to me and asked, "The other customer has already asked me something and what else did you ask?" I smiled at him, "I didn't have any more question, I just wanted to say THANK YOU from the bottom of my heart for your helpful manner!" He beamed at me. For a few moments his eyes stayed on me. Then everyone went his own way.
