The manager at the meat counter was clearly appalled to hear his colleague K tease one of his best customers (me) for her absent-mindedness. When she then asked me to fetch her a frozen banana-flavoured Yazoo drink from the chilled drinks section of the supermarket, he had no choice but to intervene.

Everything made sense when we explained to him that K knew me quite well from her second job, that we were good friends on Facebook, and I was perfectly happy to buy her a milkshake drink.

In the event they had run out of banana Yazoos, so K got to sample the new chilled coffee range instead.
