Demolition Worker Question:

I have dealt with numerous difficult customers in the past. I have found that the best method is to avoid arguing is to simply apologize. Regardless if the customer is in the wrong, it is not worth the hassle, and I definitely would not want to make a scene in front of everyone else in the building. I would then provide the customer with a new beverage or food item of their choice. I believe that smoothing everything out in a professional manner is the best way to move past the situation and to ensure the customer would be willing to return to the shop in the future.
