I don't want to pay $200 for a post-reception party.
Are your friends important to warrant such expenses?
Hmm, not anymore since I found out that they are all stingy And wouldn't do it themselves.
It may suck, but you already agreed to go so you still have to pay up. After this you don't need to associate with those friends anymore if they are too cheap for you. It's best to stop relationships now before things get worse.
Maybe I will just pick up the check and then ghost. Or better yet, I'll show others the receipt later, so they know the truth about what happened.
As long as you pay everything will be okay. It's your duty if you agreed to it.
