>>37148032Stores will basically take anything back if you're adamant enough because the customer is always right, especially if you're not overly aggressive and you let it be known you're willing to shit talk them to higher ups.
Apathy is also a thing retail tends to breed so unless they've been specifically told off for it before, they'll generally let anything slide without even questioning it as long as it isn't obviously not true.
Hell, one of my cheap ass cunt older sisters has brought back her kids sneakers after over a year of use and gotten a refund before.
Realistically they'd get away with whatever if you let them, especially where I am in Canada since the consumer law in my province basically tells you whatever the business says goes but only corporate makes enough to give a shit about the actual rules they've made up.
