Not a fan of making fun of accessibility aids, even if they are being used for what seems like a silly reason to some, it can give those who legitimately need them (and we don't actually know that the person in the photo doesn't, do we?) the message that they would be mocked if anyone found out about them using something they need (unless they disclosed their disability and explained why they need them to what is likely a bunch of strangers).
Not trying to have a go at you OP, just saying - inclusivity matters, and it includes considering and being welcoming to people with all needs.
