"Hello, can I help you?"
"Yes ma'am, I have a package here for John* that requires a signature. Is he home?"
"Oh...um...I usually sign for his packages without any incident. Is that alright?"
"Well, ma'am, normally I wouldn't mind, but my manager has been coming down on us lately for packages that don't make it to their destination."
"Oh, of course, I see." *Continues in a quieter voice* "Well, hopefully you can be discreet...this is kind of embarrassing, but I am John."
"Um, no offense ma'am, but you don't look like a man to me. Do you have proof, like a driver's license or similar?"
"Hmm...my license has my picture as a man. Can you compare it to my face and then let me sign?"
"Again...I'm awfully sorry ma'am. You could be a sister or a relative. I really need to leave this with the intended recipient."
"Well, what if I show you my license, prove to you I'm a man, and my wife vouches for me? Would you let me sign then?"
"I guess that would be using due diligence."
"Great. Why don't you come inside and make yourself comfortable while I get my wife and license. Then I'll be more than happy to let you check me out yourself."
