Customer at service desk discovers her invisibility shield malfunctioned

While getting served at a check out desk to sign up for cooking classes, other customers seemed to keep moving themselves in front of the woman getting served. Even though the clerk could see the woman she was serving, it seemed that some customers were experiencing some kind of blinded shield in thinking that nobody was in front of the clerk and kept coming in front of the woman while in the midst of the transaction. Apparently the woman’s invisibility button was malfunctioning for those times when she didn’t want to be noticed to times when she needed to be noticed.
