There are 2 very sweet Nuns that come into the store every couple of days or so. They have the best sense of humor, and I absolutely love to tease them, and they can give it back just as well.
Last Saturday, I was taking care of a customer, and I noticed they were behind him in line. I leaned over the counter, and in a stage whisper said, "Watch out for those 2, that's just a costume they are wearing."
He looks at them, and starts stuttering, "You can't tease the Nuns, you can get struck by lightening."
To them he says, "Make sure I'm out of the way when you strike her, I don't want to get hit."
From the Nuns, I get "Oh, you..." but they are laughing.
The customer is still stuttering, and every once in a while swearing, as that is just his normal chatter. Then he realizes he was swearing...in front of the Nuns. That was funny, as then he didn't know what to say.
After he left, the Sisters and I were laughing, and they loved his reaction as much as I did.
A couple days ago, they came through my line again. After they left, I noticed something on the floor, when I was taking care of another customer. Upon closer inspection, I noticed it was a Rosary. I grabbed it, and looked up, and saw they were just leaving the lobby. I told my customer I would be right back, and ran to give it back.
As I handed it to her, I said, "Wow, it didn't burn."
She just shook her head and said "Oh, you." and laughed.
