"Usually it is people eating the bulbs thinking they are onions."
On that note, I once made a huge fool of myself in a posh Thailand hotel. I had dined in the restaurant - beautiful food - with my wife, and as we walked back out into the vast hotel lobby I noticed, by the entrance to the restaurant a small table, on which was a big bowl piled high with choice Macadamia nuts, a particular favourite of mine. Being a greedy pig I grabbed a handful of the nuts and stuffed them into my mouth, chomping greedily.
You've guessed it, they weren't nuts but big, juicy, industrial strength peeled garlic cloves. The lobby was crowded with sophisticated people, and there I was, with my mouth on fire, unable to do anything but run for the ornamental fish fountain and give the exotic fish a garlic meal.
My wife made for the lift, not wanting to be associated with the man that everyone was staring at.
