I have worked in customer service and retail for years. I've seen a lot of crazy stuff, but today I'm going to talk about something that boggles my mind: customers who don't want me to ask them questions.
White or brown bread on your sandwich? Do you want cheese on your burger? What kind of drink would you like? How many gigabytes do you need in your USB drive? If I don't ask these questions, how would I know what you want? I think these people expect me to read their minds or something.
What would you do if you were the customer and the employee didn't ask you what you wanted, and you got something that wasn't right?
You know what? I'll tell you a secret: the customer is not always right. ;)
