In a marketing campaign, that I assume was meant to be based on Valentine's Day (maybe?), Delta Airlines and Coca-Cola distributed napkins to passengers encouraging them to write their name and number on the back of the napkin and give it to their "plane crush". On the opposite side, the napkin read "because you're on a plane full of interesting people and hey...you never know".
Some passengers looked at the napkins and thought nothing of it. Others were offended with one even saying that it "encourages affairs".
Others found the napkins to be creepy and said that no one appreciates unsolicited phone numbers.
Delta and Coca-Cola have since made statements apologizing for the napkins. In a statement, Delta said,
"We rotate Coke products regularly as part of our brand partnership, but missed the mark with this one. We are sorry for that and began removing the napkins from our aircraft in January."
Coca-Cola has also apologized to anyone that was offended by the napkins and has begun replacing them with other designs.
