Thank god its a good while since someone said this to me, as i dont pander. But ive heard of other friends with SEN or online groups that this kind of thing is still rife, "well meaning relatives" suggesting these after seeing said and handful of times each year 
, i do remember those really awkward, wtf kind of conversations with well meaning people, but why do people do it? Aswell as often making the person look foolish or uninformed i find its its quite arrogant actually and carries an assumption they know better than you. I do appreciate some people might feel they are being helpful but i suspect its a small group.
