Does Guilford need another grocery store or coffee shop?

Recent updates from "The Connecticut Scoop" indicate the the new rock pile, "Guilford Village West", will be home to an Aldi and a Starbucks.
The former will be the *fifth* grocery store in Guilford (a town of less than 23,000 people). What will Aldi bring to our town that Bishops, Big Y, Fresh Market, and Foodworks don't already, aside from more asphalt?
The latter will be, at the very least, the *tenth* place to get coffee along/just off Rt 1 in Guilford. What could a Starbucks bring to our town that Cilantro, Belle Vie, Hen & Heifer, Moon Shots, The Marketplace, Dunkin, Dunkin (2x), Ciao! Angie, and our seasonal friends at Camper Coffee don't already, aside from more asphalt?
To that end, a Starbucks failed in Guilford already - lasting less than 2 years across the street from the busiest shopping plaza in town. Why will this iteration be different?
This needless oversaturation of commercial businesses puts not only an ecological strain on our environment, but a financial strain on local small business owners already competing with established chains.
