I once had to pay for both my Arby's roast beef burger and my dates.
Misandry.
And they harp on the old adage that if on your big first dinner date, the lady orders a lobster entrée, she's obligated to fuck you. Dream on.
Having seen many big first dates at the fine dining restaurants I've worked at over the years (I also co-owned a small bistro), I can tell you for a fact that splitting the bill is much more common than the folklore surrounding the event would imply. Try, 75% of the time, the couple each pay at least a portion, such as the wine and drinks, if they don't just split it down the middle. And I've witnessed women pick up the entire tab on Valentine's Day, too. When I worked at a steakhouse (Morton's), women very often picked up the bill because they brought their male date there as a surprise treat.
