This is something I've wondered about and want to know other shoppers opinions. I'm often asked in my reports if a CSR issued opening greetings and closing greeting at the register. Would you consider, "I can check you out" to be an opening greeting? Once the transaction is finished and I say, "Thank you", would "You're welcome" be a closing greeting? In a perfect world they would say, "Hello, how are you" and "Have a great day", but since it's not a perfect world, what is enough to check the "yes they did that" column?
