You can't blame 'not the store's site' for that, though. :P I've called to see if a store is open before, but it was under unusual circumstances (holiday, not my normal day working so I don't know if this is their day closed, hurricane, etc), but in those cases I say that I wanted to see if you were open today.

If the place is closed, it's unlikely anyone will answer the phone unless the caller ID shows a number they know...

I answer my work's phone all of the time after closing. There are multitude of reasons. Customer got an order wrong and while I can not fix it at the time, I can write down their name so the next time they come in we can fix it. Or an employee calling off due to emergency issues, or as others have pointed out, the website and google both had our times marked down wrong (we have since gotten that fixed). We have caller ID, but as many of our employees don't have their names connected to their phone numbers, it just shows up as "Caller XXX-XXX-XXXX" and I do not have 30+ numbers listed.

So yes, I have gotten plenty of phone calls before and after hours and will gladly tell a customer when we are open until.
