Caution . . .

stuck on yellow.

I'll always remember an encounter a group of us (us being a loose group of friends and acquaintances) had at a little eatery we once retired to after a rock concert at Essex Uni. An American was lathering his hamburger (or was it a hot dog?) with mustard as though it were the insipid American kind. We were so amazed that not one of us said anything to him . . . the expression after his first bite was priceless.
