Home Depot

I see this material was available at the Timmins store online. I checked because it is 2.5 hours round trip, over 200 km.
So I get to the store, look and see nothing so asked an associate if they could help me locate it. She said it might not be available because it's seasonal and I explained that it says it is online. She asked if I seen it or knew where it was? To which I said no. She asked if I would like to know and I said yes.
Here response was not the best for customer relations" It's in the back wrapped and stapled for the season, sorry about your luck Sir"
Why couldn't I be assisted better then that?
I didn't do anything wrong, yet I felt pretty much stunned at how this situation was handled.
