The husband apologizes for accidentally leaving a tip at a restaurant while in a hurry. The wife reminds him to be careful and reminds him to be more careful next time.

Hey, I want to tell you something that happened to me today.
gpt
Sure, what is it?
human
So, I was at the restaurant for lunch and I was in a hurry to leave, so I didn't double-check the check. But when I got back home and looked at it, I realized that I made a mistake!
gpt
What do you mean? Did you leave a tip?
human
No, I forgot to add the tax. I feel so embarrassed. I wish I could go back and fix it.
gpt
I'm sure it's not a big deal. Mistakes happen all the time.
human
I know, but I always try to be careful with these things. Remember the last time we were at that restaurant and the waiter charged us for something we didn't even order?
gpt
Yes, I remember. But you talked to the manager and they fixed it.
human
I guess you're right. I'll just have to make sure to be more careful next time.
gpt
Exactly. Don't worry too much about it. It's not worth stressing over. 
human
Thanks for understanding. I feel much better now.
