Hello!

[TheCarlisle]

I keep forgetting about your American buildings. We have old cottages and mills that have been converted into restaurants and some very fancy windows. Some are a good few hundred years old.

Aha, true. I'm from Canada, an America with a leaner waistline, more hockey arenas, trees, water and wildlife, and full healthcare

I'm not saying she did absolutely, I'm saying it's a distinct possibility. Go for the most likely, until there is evidence to suggest otherwise. Or just stick to Occam's Razer, the simplest explanation is most likely and often correct. The explanation requiring the fewest assumptions is the one you should go for. You're more likely wrong the more assumptions you make. You should only go for a more complex explanation when there is evidence to support it. It's a basic scientific principle. Use it.

But why would she lie?

Look into her personality and any possible motives. If she was the only one present, she is the first you look into. Some religious nuts have done some pretty nasty things simply because they 'believed' god told them too. Don't just assume god did it.

To quit her job?

Possible.

If she was a nut case, other coworkers would know and tell the store owner that she may have done it.

Not if they shared her crazy beliefs. Some people go around claiming god spoke to them, yet many fellow Christians see nothing unusual about it.

This shows that they trust her.

Do you?

However improbable/probable, it's still possible.

Possible? Yes, Probable? No.
Go for the most likely, then work from there. Superstition should always be last on your list, because there is no evidence to support it. Stick to Occam's Razer.

You can speculate better than that. I know you can.
I often work in the woods, sometimes I see shady objects moving in the distance. I never jumped to any conclusions. I stated the obvious then worked up from there. The obvious was: There are objects in the distance, and they're moving. It was only till later that I learnt that they were in fact cars. I never knew the road was that close. If I jumped to "goddidit", I'd feel pretty damn stupid.
Start with the obvious, then work your way up from there. You might just find out what caused that mess, then you'll notice just how silly jumping to "goddidit" was.

Sounds like an interesting job. Where are from, the Finland?

Well, I can see it takes a faithful leap (more of a hop IMHO) in believing that the girl was telling the truth and wasn't exaggerating anything. All this debate is coming down to is "I believe her!" and "No, I don't..."
