What would you think of a currency that expired on the hour, every hour?

What would you think of a currency that expired on the hour, every hour?

How about a currency that gets issued and instantly redeemed only when a transaction takes place?
Yes, this is nice. I actually do this already. But I have found that reseting every hour is a useful way to clean up. One of many possible L2 workflows.
Ways to make me even more annoyed when the cashier is taking too much time on the person in front of me.
