The duo were spotted together on Sunday at a liquor store, where the actor posed for a picture with store employee Jenna Noyes, who posted the photo on Facebook, captioning it, “Met Ben Affleck at work today.” She has since deleted the post.

Affleck and the Saturday Night Live producer visited the same store the day before. Noyes later posted a screenshot of security footage on Twitter in another post that has since been deleted. She captioned, “The one time I don’t look up at the customer AT ALL.”

It’s not clear for whom they were buying the alcohol. In March, Affleck revealed in a Facebook post that he had completed treatment for alcohol addiction, “something I’ve dealt with in the past and will continue to confront,” he wrote.

“I want to live life to the fullest and be the best father I can be. I want my kids to know there is no shame in getting help when you need it, and to be a source of strength for anyone out there who needs help but is afraid to take the first step,” the post continued.

A friend of the actor tells PEOPLE that Affleck is “committed to bettering himself and continues to stay on his path of wellness and spends time with his family.”
