I guess you missed the part where the OP explained it was a family get together to celebrate DD's birthday? I also don't think the OP said they "couldn't afford" to feed their guests - I read it that they are just trying not to be wasteful while still ensuring people enjoy their food.
I'm sure it boosts your ego for people to want "one of everything" but that doesn't mean it is necessary for everyone to have one of everything have a good time and get enough to eat. Food shouldn't be the main focus of a birthday celebration anyway - just having all the family together is the key IMO. I think it is a bit sad that you think what the OP is suggesting is "cheap" and they should not bother inviting family over to celebrate DD's birthday based on the food options available...
I guess YOU missed this part:
I don't want to seem cheap but when we do hamburgers and dogs or chicken everyone seems to want one of everything. I thought it might be more budget and streamlined if we stuck with one food and then the sides (and we will have salads too). Or we could add brats too? I just don't want people to leave hungry. What do you think?
I don't know about you but when I invite people to my home for any occasion I make sure there is enough food to go around. If I were in the situation where I couldn't afford the food or had to worry about someone taking an extra hotdog then I wouldn't invite people over to eat.
If I had to cut back on my food budget for the week to supply an extra $10 worth of meat then that's is what I would do.
How does *ego* play into not letting your guests go home hungry? So what you are saying is it's OK to invite people over to eat and then not feed them enough? That they should be thankful that they were invited at all?
If you think that's OK then you remind me of my mother's friend...she would invite us over to dinner and make ONE roasted chicken and 9 roasted potatoes for 4 adults and 5 kids. And it wasn't a matter of not being able to afford more, she was just really, how shall I put this...frugal...with feeding guests.
Sorry, I was raised by a mother who believed it was better to have too much food then too little for your guests.
You'd probably faint if you saw the amount of food we make for holidays and whenever we have people over.
