Yeah, I saw that story. Takes a lot of gall to attempt that but like others said, the retailer should've said you're out of your mind lady, take it back home. I fault the stores for creating this mindset over the years. It's a symptom of not having any good sense. Granted, I'd never try that, but human nature is to take advantage of whatever someone will allow.
The return policy of some retailers is at fault. I know they're trying to maintain a customer base but some reason needs to prevail. TSC is a good example. I see stuff returned there all the time that there is absolutely nothing wrong with. Buy a tiller, work your garden, take it back. Buy a chainsaw, cut up the trees from storm damage, return the saw (I actually bought one of those at a pretty good discount a few years back).
ON THE OTHER HAND... I bought a self igniting propane torch there the other day and it didn't work (gas wouldn't come out, tried it on several bottles) so I returned it (would've exchanged it but they were out of stock). So I go back a few days later to see if they have stocked any more and sure enough there was one on the shelf, THE ONE I RETURNED!
Now I was pretty clear that the reason I was returning it was that it did not work.
It's all a simple result of people not engaging their brains.
