After facing considerable backlash from air passengers for their controversial napkins, Delta Air Lines and Coca-Cola issued apologies on Wednesday.

The red and white napkins which featured Diet Coke logos had writings on both sides of them. “Because you’re on a plane full of interesting people and hey...you never know...” the napkin read on one side, adding on the other, “be a little old school, write down your number and give it to your plane crush. You never know…”

The napkins also provided space for one to write down their private details like name and phone number.

Although the soft drink company meant the napkins to be amusing, it rubbed some passengers the wrong way, many of whom took to Twitter to point out it was inappropriate. “Hey @Delta and @CocaCola These napkins are creepy AF. Pretty sure no one appreciated unsolicited phone numbers in the ‘good old days’ and they sure as heck don’t want the number of someone who has been gawking at them on a plane for hours today. Not a good look,” one Twitter user wrote, posting pictures of the item.

However, reactions to the napkins on social media was a mixed bag, as not everyone who came across them was outraged:

Regardless of the reactions, both Delta as well as Coca-Cola have apologized for offending some people through the napkins and assured their customers they were working on withdrawing the napkins from the market.

“We sincerely apologize to anyone we may have offended. We worked with our partners at Delta to begin removing the napkins last month and are replacing them with other designs,” a spokesperson for Coca-Cola said in a statement to Insider.

A Delta spokesperson, on the other hand, told the outlet: “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."
