Allow me to set the scene:
"Hello, Ma'am, I'm here with your weekly delivery of rats from the grocery store".
"Hold on one second, I'll be right there!"
"Come in, you can put those in the freezer, and I'll give you a tip".
"Oh, Ma'am, a tip isn't necessary, it's all part of my job..."
"No, I insist you deserve something...."
