buggy, cart, it depends
How do you leave your cart in the parking lot? Like you find others?
There is a tribal response to how people that are shopping at a store return their buggy.
Walmart is different than Costco.
Costco is different than ALDI.
Some require a deposit, be it only a quarter, to force you to return it.
Others get left in BFE.
Take a look around you when you are inside pushing a buggy.
Now look outside at the buggy drop off location.
See what I mean?
