Hi Caso-Matthew. Ok- The first thing bby employees could do is when confronted with a problem that either confuses them or is outside the norm- assume the customer is telling the truth, even if you suspect they are lying. I worked retail in both sales and management for 20 years and I know that customers sometimes lie, but have never seen a case where becoming even the slightest bit confrontational with a customer or trying to win an argument with a customer has paid off. The "blue shirts" (I dont mean the term to be pejorative) on the sales floor could simply say hello or good morning.afternoon/evening to browsing customers- opening the door to being helpful without being pushy.
