I've had this happen more than once:
Me: "Hi. I am here to look at a new phone."
Him: "Do you have an account here?"
Me: "No. I don't have an account here but I am free to sign up with anyone, as I am not in contract."
Him: "Before I can help you, I need to run your credit to see what you qualify for."
Me: "I don't want to have you run a credit check." (instructions say to politely decline a credit check)
Him: "Then, I can't help you"........ (losing eye contact with him, he starts looking around)
Me: "I just want to look at phones." (you dummy, I need to look at phones and YOU need to do your job!)
Him: "Like I said, I wish I could help you."
Me: "Can you show me the iPhone6 (I was going to push this guy UNTIL he gave me what I wanted. I was ready to do 20 minutes of pushing!)
Him: "Okay (reluctantly) I can show the iPhone6."
Me: "Oh, such a nice phone. I've been wondering about the new iPhone6."
Him: (he does not seem interested in helping me. He barely glances at the phone. He looks like he wished he were some where else..) "It has the same features pretty much as the older iPhone."
Me (OH Wow! Such great help!)
