Opposite of my apartment is Dublin there is a bunch of nightclubs. So I’m used to find empty beer bottles, glasses, cigarette butts and the occasional vomit on my doorsteps.
This morning I found a slice of cucumber and some lettuce on my steps. Now I know that some bartenders love to put cucumber in certain cocktails and once I ordered a Bloody Mary, which consisted more of lettuce and celery than of tomato juice and vodka, but this slice of cucumber was slightly too big for a cocktail.
Probably the solution to this riddle isn't too difficult. It is about time for vegans' night.
