The whole family have gone on holiday abroad but by car. There are 13 of us: mother, father, sister, brother in law, niece, brother, sister in law, nephew, husband and my 3 children.
It is a self catering holiday. We all brought stuff for the kitchen/loos - for example, I brought washing up liquid, bin bags, t-towels, 18 bottles of beer, various alcoloholic spirits, 72 jaffa cakes(!), 3 packets of Cadburys fingers, 3 large bags of Kettle chips, 6 bottles of squash, 2 loaves of bread etc.
My sister brought a large selection pack of Haribo sweets (a big bags with loads of little bags in it), 4 Cadburys family sized swiss rolls and a large bag of pasta.
My niece is very very picky on 'main' meal food and savoury food. However, she eats loads of 'junk' food such as cakes and crisps and sweets. As such she would help herself to the 'junk' food without offering anyone else anything but would eat readily of the other food I brought.
In fact my sister wouldn't share any of the food she bought on the holiday - even bread, but would accept all food offered her from others.
On the 7 days on the beach my sister and brother in law spent exactly £0, but my brother, father and I bought cofee, tea, hot chocolate and ice creams everyday - which they accepted.
Would I be unreasonable to say to her directly I am unhappy with her attitude and behaviour?
My father wants to go away next year but my husband has said no as the final straw for him was at the last meal on the last night, my brother in law ate one of the cakes my husband had bought and offered round the table and brought squirty cream (from his room!) but did not offer it to anyone else at the table.
