My future in-laws have offered to pay for the rehearsal dinner, which is wonderful and was unexpected. (My FI and I are paying for the entire wedding ourselves).
However, there is one issue. My future in-laws are completely against drinking (religious reasons I guess) and we are almost positive they will not pay for any alcohol at the rehearsal dinner. My family enjoys drinking as do my FI and I so we would like to have drinks available for those who wish to have them. We are willing to pay for the bar ourselves but we arent sure how to bring up the subject to his parents.
How can we bring this up to them or offer to pay for the alcohol ourselves without offending them or causing drama?
