This no food eating thing in a gallery is a rule for a reason.
There I was, sucking on a mint.
Mum says something to me.
It amuses me.
So much so that I managed to projectile spit my mint out of my mouth in front of what probably was a very expensive Impressionist painting, past the little rope that was 'protecting' the work of art.
Needless to say we stopped looking at that painting pretty quickly and moved on.
