In business, when a competitor is interested in your product and service, but goes to another company, they are "eating your
lunch." This happens often when a company strategy or branding is weak — the prospect is interested in what you sell, perhaps because of your marketing...hits your website... but they are not engaged. Their reaction is lukewarm, or "I
don'
t get it." They
don't know why they should pursue their interest in your product or service. So they
go elsewhere. And your competition eats your lunch. (What's for dinner?!)
