SARNIA, ONT. In Sarnia, a new pandemic craze sees businesses take verbal shots at each other through signs. Started by a local radio host, the effort is designed to give a social media boost to suffering businesses, hard hit by the lockdown. While many of the signs feature some tongue at cheek adult humour, it seems the craze is welcomed. From the outskirts to the downtown, dozens of businesses have joined the war of words. In one case, a garden centre took a shot at a trophy shop down the street. Peter Sparks, of All Seasons Trophies, fired back.
