<human>: I let for a business trip yesterday, and I'm also going snowboarding on the weekend. I brought my boarding equipment packed up in a snowboard bag.

Once I get to the airport, I check in at the kiosk and talk to the "helper" who tells me she has no idea if I need to be charged extra for the snowboard bag. So as instructed, I got to the counter. The guy is not sure what to do with the snowboard bag either and calls over his coworker. They both briefly discuss it and they say they'll check it in as a surfboard. The guy looks me straight in the face and says cheerfully, "Ok, sir that will be $150" I hand over my card to him and go, "Wait a second $150 for just the check in or for the whole trip??" $150 to ship my snowboard! At this point, I'm thinking that's just not right. It's slightly longer, but it's not fragile and doesn't need special care. I ask about three times if he's sure, to which he says, "yes, I'm sure."

So I begrudgingly pay the $150 because at this point, what choice do I have? I'm thinking of UPS-ing my gear back home now. Once I get past security and sit down, I finally think to google search the airline's policy on snowboards. It turns out, my snowboard should have been checked as regular checked luggage unless it weighed more than 50 pounds. It was around 33 with all my gear in it.

Now, this is where my extremely petty revenge comes in. The flight I'm on is almost a full flight, and we're sure to run out of cabin space for carry-on. They ask if anyone is willing to check their bags. Normally, I would have checked my bag since I already had a bag checked. **BUT NOT TODAY!!!!** I took my bag onboard with me.

Can you condense the text into three sentences or less?
<bot>: Overcharged $125 for checked luggage, refused to check my carry-on (free of charge) because the plane was running out of space.
