Lay off the stickers
When the flight attendant noticed this, she snapped this picture because she was really agitated. Although the child who sat next to her didn’t make any mess, they did put a few stickers on their plate.
The flight attendant, who was visibly furious, criticized the child’s parents on Instagram, stating that they ought to be more stringent about what their kids are allowed to do while flying. Parenting can be challenging, but forcing flight attendants to remove these stickers is not polite.
