Um, a box of what?

So on my last visit to the Gros (the KZ equivalent of Kroger) they gave me a little box of matches at the checkout. I wondered if I had won something, like maybe every 10th customer gets matches or something. Nope. Basically if they owe you 5 tenge or left, they can give you a box of matches instead of the change. Can you imagine? Let’s say you head to Walmart or Target and instead of that 10 cents you should get you get matches instead? :) The nice thing is that matches are used in every home to light the gas stove and my house was running out. Unexpected, but convenient, I’d say!
