What a bummer, Pebbles! Can you pick the peppercorns out?
When I was a teenager we went on a family day out and stopped at a burger bar before getting the train home. I picked up what I thought was a salt shaker and shook it liberally all over my salad and chips. It was sugar. The rest of the family thought it was funny. 
(It was, really. But I love my food and was gutted that it tasted so awful when I'd been really looking forward to it.
)
I'd like to put the antivaxxers in a locked room with Joe Swash. That would teach them.
