Will that work against a mugger who is armed with a piece of fresh fruit? Fresh fruit is usually considered superior to canned… more antioxidants, better flavor, and no added sugar.
Best to arm yourself with a ripe durian. As good as “mace” or bear spray – hit a mugger with this stuff and he’ll be off in an alley hurling his guts out.
(although I suppose that a can of surströmming would serve much the same purpose, if you really want to stick with cans)
