Oh my I need advice!! Our sons friend is coming on holiday with us. Thing is, how on earth do we split the bills??? They are both 17. My son has a part time job whilst at college and his friend is in an apprenticeship job. When we go out for evening meals, breakfast, whatever, how would you split the bill?? We don't want to be bank rolling them both. We only have a set amount of spending money. Obviously we drink more alcohol than them but a soft drink isn't that much cheaper when in Europe!! My head is spinning!!! X
