For The Love Of Cod.
Say fish and chips and people generally think cod and chips. But cod has been scarce in the seas lately and catches have been restricted by EU quotas. So what do you do if you're a fish and chip shop and the majority of your customers automatically ask for cod and chips?
Well, contrary to my previous advice, you short-circuit their psychological short-cut; take cod off the menu on "No-cod Wednesdays"; and make them focus on the alternatives. Partly a green initiative, but certainly smart marketing for a business that has its own Long Tail.
