"Thirty feet" ?????? ! ! ! ! ! !
Pardon my excessive punctuation, but I almost fell off my 4" heels when I read, "The garden center entrance is after all only about 30 ' from the store entrance".
OTOH, that does explain your position.
The closing of the separate garden center entrance has occurred at most Lowes, Home Depot, Walmart, Menards, and other large stores in my metropolitan area in the last several years.
These are big, sprawling places, and the walk from door to door is usually 100-120 feet, sometimes more. Not 30'
At Fleet Farm the garden center is about 250'- 275' away from the main store entrance. So they DO maintain it as a separate store, and people DO re-park.
And...you certainly don't know the people I know.
Personally I, and the people I associate with have spent many happy hours browsing in a hardware or automotive store.
So I could camp out in a store that combines hardware, home goods, groceries, garden supplies, livestock & farming, technology & entertainment, and whatever else is particular to that mega store.
The fact is people do browse, and get ideas for ways to improve their comfort, which is why all these stores have started drawing new customers by holding DIY classes.
