I never know if these stories are believable or not, but this one from monster.com struck me as something I would do:
Then, the client offers a cup of hot chocolate. As we get to the details of price, I take a gulp of my chocolate and it goes down the wrong way. I choke and spray it all over the client’s face, shirt and white trousers. I was numb. While I sat there, my bosses were running about trying to find napkins. I apologized profusely and wanted to cry. It was just one of those days.
I laughed at the story because I have experienced that immediate choke response on a few occasions. It is because of this possibility that I rarely accept coffee or other drinks at a client’s office. Better to be safe and avoid this possibility.
The client’s trousers were white – I love that part of the story.
