His parents are planning the rehearsal dinner and refusing to pay for alcohol. They say it is because they come from a Christian background and do not think it is right to pay for something like that. I think that it will cause a lot of awkward situations and that it is a celebration. They should be catering to the guests comforts and not their own. My parents offered to cover the alcohol for the event, but I feel terrible because they have paid for everything else. How should we fix this situation? Thanks for your input.
