I kinda want to say it wasn't really anger, because I didn't raise my voice, but I complained to the cashier at McDonald's because every time I order from the new Signature menu and want a side salad instead of fries, they try to charge me extra, and then I have to wait an entire minute or two until they can get someone to fix it...

LOL. I can't believe I can get my ire up over a few minutes of waiting. It seems so silly in retrospect. At least I could see myself getting angry in the moment...

I did have a hard time letting it go, at the time. I wanted the cashier to acknowledge that it was an issue that needed to be fixed. But, she kept trying to make it into a one-time thing. My point? Your restaurant has an issue. You advertise that side-salad is an option, but in reality, it's slightly more difficult to get that option, and if I'm not on my toes, you will overcharge me.
