Just the other day whilst out and about, I thought I’d pop into a local supermarket to pick up a few essentials, so in I went, scooping up a basket from the double-door entrance as I strode inside. Almost immediately, I came to the refrigerated vegetable section and realising I was short of a decent lettuce, I started to search around in the four-tiered, shelved greenery: I found pre-packed Rocket leaves, tossed salads, loose Spinach and watercress’ of various shapes and sizes but no lettuces - iceberg, curly, Gem or round - were anywhere to be seen.
