Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: Some context: I have never stolen anything, or even asked for a cup of water and then filled it up with soda, or anything like that. But this time I feel like it's maybe justified.

I was in a grocery store and felt like treating myself, so when I saw this brand of cookies I really liked on sale for $1.50, I decided to buy them. When I went to pay, I thought my total ended up being a bit high, but the line was so long and everybody had already been waiting for so long that I decided not to hold up the line since it was probably nothing. Then, when I got to my car, I unfortunately forgot to double-check the receipt, which is on me. At home the next day, I found the receipt in my pocket and checked it, then found out that they charged me $4.00. I don't know if the register glitched or something, because below the name of the cookies, it even said that they should have been $1.50, but then the number next to it said $4.00. That is so much to spend on a single box of cookies that were already kind of a splurge. I would let it go if they overcharged me by $.50 or even a dollar, but the thought of paying $2.50 extra is making me feel so guilty.

However, the store in question is kind of far away since I had stopped by it on the way back from another place, and is not my normal store, so it would cost me that much in gas to go back and get my money back. The next time I'll be up there is in a couple weeks. WIBTA if I took 1-2 dollars worth of pens or candy or something to even it out, or should I just eat the cost and take it as a lesson to double-check the receipt in the store? Either option is making me feel terrible, so I appreciate any input.
