"It should be 'Ladies first' - hope you have a great night "

Just as a general observtn - that is so, except for married·couples/partners, where husband's/male's name often comes first - from the King & Queen to Fred & Betty Jones. I used to like to refer to, sign, and so on, my late wife & me as 'Valerie & Michael' on above principle; but most of our friends would go on saying, & addressing Xmas cards &c, 'Michael & Valerie'.
