If you can't be gracious about the small things, how can God entrust you with the big ones?

Here's what happened.

Bought 2 wardrobes. The delivery wasn't as per expected. Bought tables from IKEA and incurred a slight damage while transporting it back home (poor packaging). Found myself calling both shops and wrangling with the people in charge about the incidents.

That makes me wonder, if I'm a fusspuss about these small items then how can God entrust me with biger stuff in the future?

2 x wardrobe = $168
1 x table top = $60
----------------------
Total cost = $228

That's an small amount that I'm getting worked up over!
