I just received an email invitation for a "wedding" for this couple I know very, very distantly. I say "wedding" because it is actually a "wedding tour" (their words). As they are an international couple (neither from the UK), they are throwing wedding receptions in about 5 different places. This in and of itself isn't so bad, but I received an update from the groom that we all have to pay £20 each if we want to eat and it is BYOB. We are also strictly instructed to only attend our local party. We are also instructed to give them money and airmiles to help pay for this intercontinental wedding extravaganza as they cannot afford it (of course, this is through honeyfund). Any "leftover" money will pay for them to extend the tour to more destinations so (in their words) "Give big if you want us to come to your town".
Needless to say, Fi and I will be sending a card but be "busy" that day.
