A local college-town cafe has seen footfall drop and wants one clever, low-cost referral or loyalty idea that would actually get students coming back and bringing friends.
This is a fast, one-sitting challenge. Use ChatGPT or Claude to brainstorm, then write up your best idea yourself.
WHAT TO SUBMIT (200-400 words): the referral/loyalty idea, why students would actually bother participating, and a rough estimate of what it would cost the cafe to run for a month (assume a budget under Rs 10,000).
NON-NEGOTIABLE: original write-up in your own words, must be specific to a real cafe/student context, not generic "give discounts" advice.
JUDGING: specificity and creativity (50%), realism of cost and execution (30%), clarity (20%). Top solution wins the full prize.
