furious: I was overcharged $20 at the grocery store.

I went to the grocery store last week, which is 30 miles away from my house, and when I got home, I discovered I was overcharged by $20. That made me mad!

That's terrible! Did you call and tell management?
human
Yes, I did. But now I have to wait until next month to get my money, as I only go there once a month. Grrrrrr...

Thats frustrating. At least you'll get your money back eventually.
