It's not uncommon to find a rotten spud in a shop but you found two on one trip.
I find it hard to buy anything more than an occaisional tube or bottle of lube from a place like this out of shear conveinience only.
Usually I'll drive the extra five miles to a place that deserves my patronage. Even if it's a two dollar purchase.
A place like this will blame the economy or a car friendly world when they go belly up.
