I need input on whether some strangers think this is rude. It's my dad's birthday soon and they wanted to take the whole family on vacation for it, on their dime. I've been planning the trip (they wanted me to help...which means I planned basically the whole thing and put a TON of time into it) for 6 months now. It's going to be a really nice trip. I'm super tight on money which everyone knows. I got my dad a thoughtful, nice but not extravagant at all gift a long time ago. Out of nowhere my sister and her boyfriend decide they want to hire a private chef for a night. Obviously this is going to be super expensive. I thought, well good for them and that's nice. She texts us and sends us the chef, the options, asks us what meals we want. I respond trying to be as flexible as I can because I don't know how the pricing is formulated. All set. The next day I get a text from her asking if I can give them some money for it because it's so expensive. I was honestly pretty offended...you don't offer to plan a hyper luxury service of your own volition and then after the fact ask someone who is by default included for money. It's not even as if she had asked weeks (or months) ago if I'd be interested in going in on that together...to which I would have politely responded sounds nice but no I can't afford it. So I answered I would give them a small amount (that honestly I really can't afford to give right now) but that I already got a gift and why don't they consider a less expensive gift. Is this not super rude to spring on me????
