The first ever sold cake that was my last

So let me start off with the cake was for a friends baby shower. I had known her and her husband since high school. Now originally it WAS going to be a gift however we hit a financial road block 2 months before they an their parents came for the tasting. I immediately let her know via video chat (should’ve done text) and asked if she could pay for the minimum ($80 vs $160) cost of the cake. They talked with their parents an ultimately her mom jumped at the chance to buy the cake. Now to the tasting. I baked a LOT for the tasting. Enough that they took home a dozen cupcakes. They were very pleased an id be paid day of the party. Well...that didn’t happen. Now further info i was best friends with both mom n dad to be. They’ve always known I’m rough around the edges an roughhouse (don’t anymore) I was asked by mom to be very nicely not to do so as it may trigger dad to be. Of course I absolutely agreed! She felt bad asking it knowing how I am an I told her not to feel bad at all! I wanted her to be honest with me 100% an if it’s a trigger then I’ll simply not roughhouse with him like we always did. Easy. He thought it was a silly request tho an said he thought no issue with it. Anyway. Day of the party came an they loved the cake. I asked the mom to be if her mom had the money owed as she’s my client not her mom. I also wasn’t comfortable asking her mother as I didn’t know her at all. Well mom didn’t have the money an said she’d get it to me another day. I shrugged an said ok thinkin nothing of it. A week goes by. Nothing. Text mom to be. Mom still doesn’t have the money. Another week. Still NOTHING. But suddenly I’m getting texts from BOTH grandmothers to be to stop harassing their kids or I’ll be sued? That the cake wasn’t good enough to buy? They ate ALL of it! I literally asked 3-4 times in 3 weeks for the money! That was a 2 tier fully decorated, organic, made from scratch cake! Apparently dad to be’s mom wanted to ‘sue me’ for roughhousing with her son? Lady he was with his wife most the time! I didn’t touch him besides a pat on the back! Then they complained how it was a ah move to request money on a ‘free cake’ I told them we could try to scrounge up the money from somewhere if needed! THEY agreed to pay! So reddit... AITA or were they being entitled ah? Note: this was 2 years ago now. We ultimately let it go to avoid trouble but I’ve refused to make cakes anymore besides for siblings an my own kids.Edit to add: the reason behind not being able to do it as a gift was because of financial issues regarding my daughter having a hospital visit. Which THEY KNEW OF and understood. We still offered to scrounge up the money from somewhere if needed but they had no problem with it at the time when it was discussed knowing the situation via /r/JustNoFriend https://ift.tt/2HHBNhl
