A friend of mine has two sisters, both of them are organising a baby shower for her. They have sent the invite out (via Facebook) and are requesting that we all give money to them (on the day or before) to pay for the costs.
I'm assuming this is the cost of the food/drink because it's being hosted at one of the sisters houses.
Now I wouldn't mind in the slightest if they said please could you contribute by bringing food with you, but I think asking for money and then probably expecting you to turn up with a gift is rather crass?
